Using OpenID Connect (OIDC) Multi-Tenancy

This guide demonstrates how your OpenID Connect (OIDC) application can support multi-tenancy so that you can serve multiple tenants from a single application. Tenants can be distinct realms or security domains within the same OpenID Provider or even distinct OpenID Providers.

When serving multiple customers from the same application (e.g.: SaaS), each customer is a tenant. By enabling multi-tenancy support to your applications you are allowed to also support distinct authentication policies for each tenant even though if that means authenticating against different OpenID Providers, such as Keycloak and Google.

Please read the Using OpenID Connect to Protect Service Applications guide if you need to authorize a tenant using Bearer Token Authorization.

Please read the Using OpenID Connect to Protect Web Applications guide if you need to authenticate and authorize a tenant using OpenId Connect Authorization Code Flow.

Prerequisites

To complete this guide, you need:

  • less than 15 minutes

  • an IDE

  • JDK 11+ installed with JAVA_HOME configured appropriately

  • Apache Maven 3.8.1+

  • jq tool

  • Docker

Architecture

In this example, we build a very simple application which offers a single land page:

  • /{tenant}

The land page is served by a JAX-RS Resource and shows information obtained from the OpenID Provider about the authenticated user and the current tenant.

Solution

We recommend that you follow the instructions in the next sections and create the application step by step. However, you can go right to the completed example.

Clone the Git repository: git clone https://github.com/quarkusio/quarkus-quickstarts.git, or download an archive.

The solution is located in the security-openid-connect-multi-tenancy-quickstart directory.

Creating the Maven Project

First, we need a new project. Create a new project with the following command:

mvn io.quarkus.platform:quarkus-maven-plugin:2.5.1.Final:create \
    -DprojectGroupId=org.acme \
    -DprojectArtifactId=security-openid-connect-multi-tenancy-quickstart \
    -Dextensions="oidc,resteasy-jackson" \
    -DnoExamples
cd security-openid-connect-multi-tenancy-quickstart

If you already have your Quarkus project configured, you can add the oidc extension to your project by running the following command in your project base directory:

./mvnw quarkus:add-extension -Dextensions="oidc"

This will add the following to your pom.xml:

<dependency>
    <groupId>io.quarkus</groupId>
    <artifactId>quarkus-oidc</artifactId>
</dependency>

Writing the application

Let’s start by implementing the /{tenant} endpoint. As you can see from the source code below it is just a regular JAX-RS resource:

package org.acme.quickstart.oidc;

import javax.inject.Inject;
import javax.ws.rs.GET;
import javax.ws.rs.Path;

import org.eclipse.microprofile.jwt.JsonWebToken;

import io.quarkus.oidc.IdToken;

@Path("/{tenant}")
public class HomeResource {

    /**
     * Injection point for the ID Token issued by the OpenID Connect Provider
     */
    @Inject
    @IdToken
    JsonWebToken idToken;

    /**
     * Returns the tokens available to the application. This endpoint exists only for demonstration purposes, you should not
     * expose these tokens in a real application.
     *
     * @return the landing page HTML
     */
    @GET
    public String getHome() {
        StringBuilder response = new StringBuilder().append("<html>").append("<body>");

        response.append("<h2>Welcome, ").append(this.idToken.getClaim("email").toString()).append("</h2>\n");
        response.append("<h3>You are accessing the application within tenant <b>").append(idToken.getIssuer()).append(" boundaries</b></h3>");

        return response.append("</body>").append("</html>").toString();
    }
}

In order to resolve the tenant from incoming requests and map it to a specific quarkus-oidc tenant configuration in application.properties, you need to create an implementation for the io.quarkus.oidc.TenantResolver interface.

package org.acme.quickstart.oidc;

import javax.enterprise.context.ApplicationScoped;

import io.quarkus.oidc.TenantResolver;
import io.vertx.ext.web.RoutingContext;

@ApplicationScoped
public class CustomTenantResolver implements TenantResolver {

    @Override
    public String resolve(RoutingContext context) {
        String path = context.request().path();
        String[] parts = path.split("/");

        if (parts.length == 0) {
            // resolve to default tenant configuration
            return null;
        }

        return parts[1];
    }
}

From the implementation above, tenants are resolved from the request path so that in case no tenant could be inferred, null is returned to indicate that the default tenant configuration should be used.

=== If you also use Hibernate ORM multitenancy and both OIDC and Hibernate ORM tenant IDs are the same and must be extracted from the Vert.x RoutingContext then you can pass the tenant id from the OIDC Tenant Resolver to the Hibernate ORM Tenant Resolver as a RoutingContext attribute, for example:
public class CustomTenantResolver implements TenantResolver {

    @Override
    public String resolve(RoutingContext context) {
        String tenantId = extractTenantId(context);
        context.put("tenantId", tenantId);
        return tenantId;
    }
}

===

Configuring the application

# Default Tenant Configuration
quarkus.oidc.auth-server-url=http://localhost:8180/auth/realms/quarkus
quarkus.oidc.client-id=multi-tenant-client
quarkus.oidc.application-type=web-app

# Tenant A Configuration
quarkus.oidc.tenant-a.auth-server-url=http://localhost:8180/auth/realms/tenant-a
quarkus.oidc.tenant-a.client-id=multi-tenant-client
quarkus.oidc.tenant-a.application-type=web-app

# HTTP Security Configuration
quarkus.http.auth.permission.authenticated.paths=/*
quarkus.http.auth.permission.authenticated.policy=authenticated

The first configuration is the default tenant configuration that should be used when the tenant can not be inferred from the request. This configuration is using a Keycloak instance to authenticate users.

The second configuration is the configuration that will be used when an incoming request is mapped to the tenant tenant-a.

Note that both configurations map to the same Keycloak server instance while using distinct realms.

You can define multiple tenants in your configuration file, just make sure they have a unique alias so that you can map them properly when resolving a tenant from your TenantResolver implementation.

Google OpenID Provider Configuration

In order to set-up the tenant-a configuration to use Google OpenID Provider, you need to create a project as described here.

Once you create the project and have your project’s client_id and client_secret, you can try to configure a tenant as follows:

# Tenant configuration using Google OpenID Provider
quarkus.oidc.tenant-b.auth-server-url=https://accounts.google.com
quarkus.oidc.tenant-b.application-type=web-app
quarkus.oidc.tenant-b.client-id={GOOGLE_CLIENT_ID}
quarkus.oidc.tenant-b.credentials.secret={GOOGLE_CLIENT_SECRET}
quarkus.oidc.tenant-b.token.issuer=https://accounts.google.com
quarkus.oidc.tenant-b.authentication.scopes=email,profile,openid

Starting and Configuring the Keycloak Server

To start a Keycloak Server you can use Docker and just run the following command:

docker run --name keycloak -e KEYCLOAK_USER=admin -e KEYCLOAK_PASSWORD=admin -p 8180:8080 quay.io/keycloak/keycloak:{keycloak version}

You should be able to access your Keycloak Server at localhost:8180/auth.

Log in as the admin user to access the Keycloak Administration Console. Username should be admin and password admin.

Now, follow the steps below to import the realms for the two tenants:

For more details, see the Keycloak documentation about how to create a new realm.

Running and Using the Application

Running in Developer Mode

To run the microservice in dev mode, use ./mvnw clean compile quarkus:dev.

Running in JVM Mode

When you’re done playing with "dev-mode" you can run it as a standard Java application.

First compile it:

./mvnw package

Then run it:

java -jar target/quarkus-app/quarkus-run.jar

Running in Native Mode

This same demo can be compiled into native code: no modifications required.

This implies that you no longer need to install a JVM on your production environment, as the runtime technology is included in the produced binary, and optimized to run with minimal resource overhead.

Compilation will take a bit longer, so this step is disabled by default; let’s build again by enabling the native profile:

./mvnw package -Pnative

After getting a cup of coffee, you’ll be able to run this binary directly:

./target/security-openid-connect-multi-tenancy-quickstart-runner

Testing the Application

To test the application, you should open your browser and access the following URL:

If everything is working as expected, you should be redirected to the Keycloak server to authenticate. Note that the requested path defines a default tenant which we don’t have mapped in the configuration file. In this case, the default configuration will be used.

In order to authenticate to the application you should type the following credentials when at the Keycloak login page:

  • Username: alice

  • Password: alice

After clicking the Login button you should be redirected back to the application.

If you try now to access the application at the following URL:

You should be redirected again to the login page at Keycloak. However, now you are going to authenticate using a different realm.

In both cases, if the user is successfully authenticated, the landing page will show the user’s name and e-mail. Even though user alice exists in both tenants, for the application they are distinct users belonging to different realms/tenants.

Programmatically Resolving Tenants Configuration

If you need a more dynamic configuration for the different tenants you want to support and don’t want to end up with multiple entries in your configuration file, you can use the io.quarkus.oidc.TenantConfigResolver.

This interface allows you to dynamically create tenant configurations at runtime:

package io.quarkus.it.keycloak;

import javax.enterprise.context.ApplicationScoped;
import java.util.function.Supplier;

import io.smallrye.mutiny.Uni;
import io.quarkus.oidc.OidcTenantConfig;
import io.quarkus.oidc.TenantConfigResolver;
import io.vertx.ext.web.RoutingContext;

@ApplicationScoped
public class CustomTenantConfigResolver implements TenantConfigResolver {

    @Override
    public Uni<OidcTenantConfig> resolve(RoutingContext context, TenantConfigResolver.TenantConfigRequestContext requestContext) {
        String path = context.request().path();
        String[] parts = path.split("/");

        if (parts.length == 0) {
            // resolve to default tenant configuration
            return null;
        }

        if ("tenant-c".equals(parts[1])) {
            // Do 'return requestContext.runBlocking(createTenantConfig());'
            // if a blocking call is required to create a tenant config
            return Uni.createFromItem(createTenantConfig());
        }

        // resolve to default tenant configuration
        return null;
    }

    private Supplier<OidcTenantConfig> createTenantConfig() {
        final OidcTenantConfig config = new OidcTenantConfig();

        config.setTenantId("tenant-c");
        config.setAuthServerUrl("http://localhost:8180/auth/realms/tenant-c");
        config.setClientId("multi-tenant-client");
        OidcTenantConfig.Credentials credentials = new OidcTenantConfig.Credentials();

        credentials.setSecret("my-secret");

        config.setCredentials(credentials);

        // any other setting support by the quarkus-oidc extension

        return () -> config;
    }
}

The OidcTenantConfig returned from this method is the same used to parse the oidc namespace configuration from the application.properties. You can populate it using any of the settings supported by the quarkus-oidc extension.

Tenant Resolution for OIDC 'web-app' applications

Several options are available for selecting the tenant configuration which should be used to secure the current HTTP request for both service and web-app OIDC applications, such as:

  • Check URL paths, for example, a tenant-service configuration has to be used for the "/service" paths, while a tenant-manage configuration - for the "/management" paths

  • Check HTTP headers, for example, with a URL path always being '/service', a header such as "Realm: service" or "Realm: management" can help selecting between the tenant-service and tenant-manage configurations

  • Check URL query parameters - it can work similarly to the way the headers are used to select the tenant configuration

All these options can be easily implemented with the custom TenantResolver and TenantConfigResolver implementations for the OIDC service applications.

However, due to an HTTP redirect required to complete the code authentication flow for the OIDC web-app applications, a custom HTTP cookie may be needed to select the same tenant configuration before and after this redirect request because:

  • URL path may not be the same after the redirect request if a single redirect URL has been registered in the OIDC Provider - the original request path can be restored but after the the tenant configuration is resolved

  • HTTP headers used during the original request are not available after the redirect

  • Custom URL query parameters are restored after the redirect but after the tenant configuration is resolved

One option to ensure the information for resolving the tenant configurations for web-app applications is available before and after the redirect is to use a cookie, for example:

package org.acme.quickstart.oidc;

import java.util.List;

import javax.enterprise.context.ApplicationScoped;

import io.quarkus.oidc.TenantResolver;
import io.vertx.core.http.Cookie;
import io.vertx.ext.web.RoutingContext;

@ApplicationScoped
public class CustomTenantResolver implements TenantResolver {

    @Override
    public String resolve(RoutingContext context) {
        List<String> tenantIdQuery = context.queryParam("tenantId");
        if (!tenantIdQuery.isEmpty()) {
            String tenantId = tenantIdQuery.get(0);
            context.addCookie(Cookie.cookie("tenant", tenantId));
            return tenantId;
        } else if (context.cookieMap().containsKey("tenant")) {
            return context.getCookie("tenant").getValue();
        }

        return null;
    }
}

Disabling Tenant Configurations

Custom TenantResolver and TenantConfigResolver implementations may return null if no tenant can be inferred from the current request and a fallback to the default tenant configuration is required.

If it is expected that the custom resolvers will always infer a tenant then the default tenant configuration is not needed. One can disable it with the quarkus.oidc.tenant-enabled=false setting.

Note that tenant specific configurations can also be disabled, for example: quarkus.oidc.tenant-a.tenant-enabled=false.

Configuration Reference

Configuration property fixed at build time - All other configuration properties are overridable at runtime

Configuration property

Type

Default

If DevServices has been explicitly enabled or disabled. When DevServices is enabled Quarkus will attempt to automatically configure and start Keycloak when running in Dev or Test mode and when Docker is running.

boolean

true

The container image name to use, for container based DevServices providers. Image with a WildFly based Keycloak distribution is used by default. Image with a Quarkus based Keycloak-X distribution can be selected instead, for example: 'quay.io/keycloak/keycloak-x:15.0.2'. Note Keycloak-X and Keycloak images are initialized differently. By default, Dev Services for Keycloak will assume it is a Keycloak-X image if the image name contains a 'keycloak-x' string. Set 'quarkus.devservices.keycloak.keycloak-x-image' to override this check.

string

quay.io/keycloak/keycloak:15.0.2

If Keycloak-X image is used. By default, Dev Services for Keycloak will assume a Keycloak-X image is used if the image name contains a 'keycloak-x' string. Set 'quarkus.devservices.keycloak.keycloak-x-image' to override this check which may be necessary if you build custom Keycloak-X or Keycloak images. You do not need to set this property if the default check works.

boolean

Indicates if the Keycloak container managed by Quarkus Dev Services is shared. When shared, Quarkus looks for running containers using label-based service discovery. If a matching container is found, it is used, and so a second one is not started. Otherwise, Dev Services for Keycloak starts a new container. The discovery uses the quarkus-dev-service-label label. The value is configured using the service-name property. Container sharing is only used in dev mode.

boolean

true

The value of the quarkus-dev-service-keycloak label attached to the started container. This property is used when shared is set to true. In this case, before starting a container, Dev Services for Keycloak looks for a container with the quarkus-dev-service-keycloak label set to the configured value. If found, it will use this container instead of starting a new one. Otherwise it starts a new container with the quarkus-dev-service-keycloak label set to the specified value. Container sharing is only used in dev mode.

string

quarkus

The class or file system path to a Keycloak realm file which will be used to initialize Keycloak.

string

The JAVA_OPTS passed to the keycloak JVM

string

The Keycloak realm name. This property will be used to create the realm if the realm file pointed to by the 'realm-path' property does not exist, default value is 'quarkus' in this case. If the realm file pointed to by the 'realm-path' property exists then it is still recommended to set this property for Dev Services for Keycloak to avoid parsing the realm file in order to determine the realm name.

string

Indicates if the Keycloak realm has to be created when the realm file pointed to by the 'realm-path' property does not exist. Disable it if you’d like to create a realm using Keycloak Administration Console or Keycloak Admin API from io.quarkus.test.common.QuarkusTestResourceLifecycleManager.

boolean

true

Optional fixed port the dev service will listen to. If not defined, the port will be chosen randomly.

int

The Keycloak users map containing the user name and password pairs. If this map is empty then two users, 'alice' and 'bob' with the passwords matching their names will be created. This property will be used to create the Keycloak users if the realm file pointed to by the 'realm-path' property does not exist.

Map<String,String>

The Keycloak user roles. If this map is empty then a user named 'alice' will get 'admin' and 'user' roles and all other users will get a 'user' role. This property will be used to create the Keycloak roles if the realm file pointed to by the 'realm-path' property does not exist.

Map<String,String>

If the OIDC extension is enabled.

boolean

true

Grant type which will be used to acquire a token to test the OIDC 'service' applications

client, password, code, implicit

The WebClient timeout. Use this property to configure how long an HTTP client used by Dev UI handlers will wait for a response when requesting tokens from OpenId Connect Provider and sending them to the service endpoint.

Duration

Enable the registration of the Default TokenIntrospection and UserInfo Cache implementation bean. Note it only allows to use the default implementation, one needs to configure it in order to activate it, please see OidcConfig#tokenCache.

boolean

true

The base URL of the OpenID Connect (OIDC) server, for example, https://host:port/auth. OIDC discovery endpoint will be called by default by appending a '.well-known/openid-configuration' path to this URL. Note if you work with Keycloak OIDC server, make sure the base URL is in the following format: https://host:port/auth/realms/{realm} where {realm} has to be replaced by the name of the Keycloak realm.

string

Enables OIDC discovery. If the discovery is disabled then the 'token-path' property must be configured.

boolean

true

Relative path of the OIDC token endpoint which issues access and refresh tokens using either 'client_credentials' or 'password' grants

string

The client-id of the application. Each application has a client-id that is used to identify the application

string

The maximum amount of time connecting to the currently unavailable OIDC server will be attempted for. The number of times the connection request will be repeated is calculated by dividing the value of this property by 2. For example, setting it to 20S will allow for requesting the connection up to 10 times with a 2 seconds delay between the retries. Note this property is only effective when the initial OIDC connection is created, for example, when requesting a well-known OIDC configuration. Use the 'connection-retry-count' property to support trying to re-establish an already available connection which may have been dropped.

Duration

The number of times an attempt to re-establish an already available connection will be repeated for. Note this property is different to the connection-delay property which is only effective during the initial OIDC connection creation. This property is used to try to recover the existing connection which may have been temporarily lost. For example, if a request to the OIDC token endpoint fails due to a connection exception then the request will be retried for a number of times configured by this property.

int

3

The amount of time after which the current OIDC connection request will time out.

Duration

10S

The maximum size of the connection pool used by the WebClient

int

Client secret which is used for a client_secret_basic authentication method. Note that a 'client-secret.value' can be used instead but both properties are mutually exclusive.

string

The client secret value - it will be ignored if 'secret.key' is set

string

The CredentialsProvider name which should only be set if more than one CredentialsProvider is registered

string

The CredentialsProvider client secret key

string

basic, post

If provided, indicates that JWT is signed using a secret key

string

The CredentialsProvider name which should only be set if more than one CredentialsProvider is registered

string

The CredentialsProvider client secret key

string

If provided, indicates that JWT is signed using a private key in PEM or JWK format

string

If provided, indicates that JWT is signed using a private key from a key store

string

A parameter to specify the password of the key store file. If not given, the default ("password") is used.

string

string

JWT life-span in seconds. It will be added to the time it was issued at to calculate the expiration time.

int

10

The host (name or IP address) of the Proxy. Note: If OIDC adapter needs to use a Proxy to talk with OIDC server (Provider), then at least the "host" config item must be configured to enable the usage of a Proxy.

string

The port number of the Proxy. Default value is 80.

int

80

The username, if Proxy needs authentication.

string

The password, if Proxy needs authentication.

string

Certificate validation and hostname verification, which can be one of the following values from enum Verification. Default is required.

required, certificate-validation, none

An optional trust store which holds the certificate information of the certificates to trust

path

A parameter to specify the password of the trust store file.

string

A parameter to specify the alias of the trust store certificate.

string

A unique tenant identifier. It must be set by TenantConfigResolver providers which resolve the tenant configuration dynamically and is optional in all other cases.

string

If this tenant configuration is enabled.

boolean

true

The application type, which can be one of the following values from enum ApplicationType.

web-app, service, hybrid

service

Relative path of the OIDC authorization endpoint which authenticates the users. This property must be set for the 'web-app' applications if OIDC discovery is disabled. This property will be ignored if the discovery is enabled.

string

Relative path of the OIDC userinfo endpoint. This property must only be set for the 'web-app' applications if OIDC discovery is disabled and 'authentication.user-info-required' property is enabled. This property will be ignored if the discovery is enabled.

string

Relative path of the OIDC RFC7662 introspection endpoint which can introspect both opaque and JWT tokens. This property must be set if OIDC discovery is disabled and 1) the opaque bearer access tokens have to be verified or 2) JWT tokens have to be verified while the cached JWK verification set with no matching JWK is being refreshed. This property will be ignored if the discovery is enabled.

string

Relative path of the OIDC JWKS endpoint which returns a JSON Web Key Verification Set. This property should be set if OIDC discovery is disabled and the local JWT verification is required. This property will be ignored if the discovery is enabled.

string

Relative path of the OIDC end_session_endpoint. This property must be set if OIDC discovery is disabled and RP Initiated Logout support for the 'web-app' applications is required. This property will be ignored if the discovery is enabled.

string

Public key for the local JWT token verification. OIDC server connection will not be created when this property is set.

string

Path to the claim containing an array of groups. It starts from the top level JWT JSON object and can contain multiple segments where each segment represents a JSON object name only, example: "realm/groups". Use double quotes with the namespace qualified claim names. This property can be used if a token has no 'groups' claim but has the groups set in a different claim.

string

Separator for splitting a string which may contain multiple group values. It will only be used if the "role-claim-path" property points to a custom claim whose value is a string. A single space will be used by default because the standard 'scope' claim may contain a space separated sequence.

string

Source of the principal roles.

idtoken, accesstoken, userinfo

Expected issuer 'iss' claim value. Note this property overrides the issuer property which may be set in OpenId Connect provider’s well-known configuration. If the iss claim value varies depending on the host/IP address or tenant id of the provider then you may skip the issuer verification by setting this property to 'any' but it should be done only when other options (such as configuring the provider to use the fixed iss claim value) are not possible.

string

Expected audience 'aud' claim value which may be a string or an array of strings.

list of string

Expected token type

string

Life span grace period in seconds. When checking token expiry, current time is allowed to be later than token expiration time by at most the configured number of seconds. When checking token issuance, current time is allowed to be sooner than token issue time by at most the configured number of seconds.

int

Name of the claim which contains a principal name. By default, the 'upn', 'preferred_username' and sub claims are checked.

string

Refresh expired ID tokens. If this property is enabled then a refresh token request will be performed if the ID token has expired and, if successful, the local session will be updated with the new set of tokens. Otherwise, the local session will be invalidated and the user redirected to the OpenID Provider to re-authenticate. In this case the user may not be challenged again if the OIDC provider session is still active. For this option be effective the authentication.session-age-extension property should also be set to a non-zero value since the refresh token is currently kept in the user session. This option is valid only when the application is of type ApplicationType#WEB_APP}.

boolean

false

Refresh token time skew in seconds. If this property is enabled then the configured number of seconds is added to the current time when checking whether the access token should be refreshed. If the sum is greater than this access token’s expiration time then a refresh is going to happen. This property will be ignored if the 'refresh-expired' property is not enabled.

Duration

Forced JWK set refresh interval in minutes.

Duration

10M

Custom HTTP header that contains a bearer token. This option is valid only when the application is of type ApplicationType#SERVICE}.

string

Allow the remote introspection of JWT tokens when no matching JWK key is available. Note this property is set to 'true' by default for backward-compatibility reasons and will be set to false instead in one of the next releases. Also note this property will be ignored if JWK endpoint URI is not available and introspecting the tokens is the only verification option.

boolean

true

Allow the remote introspection of the opaque tokens. Set this property to 'false' if only JWT tokens are expected.

boolean

true

The relative path of the logout endpoint at the application. If provided, the application is able to initiate the logout through this endpoint in conformance with the OpenID Connect RP-Initiated Logout specification.

string

Relative path of the application endpoint where the user should be redirected to after logging out from the OpenID Connect Provider. This endpoint URI must be properly registered at the OpenID Connect Provider as a valid redirect URI.

string

Relative path for calculating a "redirect_uri" query parameter. It has to start from a forward slash and will be appended to the request URI’s host and port. For example, if the current request URI is 'https://localhost:8080/service' then a 'redirect_uri' parameter will be set to 'https://localhost:8080/' if this property is set to '/' and be the same as the request URI if this property has not been configured. Note the original request URI will be restored after the user has authenticated if 'restorePathAfterRedirect' is set to 'true'.

string

If this property is set to 'true' then the original request URI which was used before the authentication will be restored after the user has been redirected back to the application. Note if redirectPath property is not set the the original request URI will be restored even if this property is disabled.

boolean

false

Remove the query parameters such as 'code' and 'state' set by the OIDC server on the redirect URI after the user has authenticated by redirecting a user to the same URI but without the query parameters.

boolean

true

Both ID and access tokens are fetched from the OIDC provider as part of the authorization code flow. ID token is always verified on every user request as the primary token which is used to represent the principal and extract the roles. Access token is not verified by default since it is meant to be propagated to the downstream services. The verification of the access token should be enabled if it is injected as a JWT token. Access tokens obtained as part of the code flow will always be verified if quarkus.oidc.roles.source property is set to accesstoken which means the authorization decision will be based on the roles extracted from the access token. Bearer access tokens are always verified.

boolean

false

Force 'https' as the 'redirect_uri' parameter scheme when running behind an SSL terminating reverse proxy. This property, if enabled, will also affect the logout post_logout_redirect_uri and the local redirect requests.

boolean

false

list of string

If enabled the state, session and post logout cookies will have their 'secure' parameter set to 'true' when HTTP is used. It may be necessary when running behind an SSL terminating reverse proxy. The cookies will always be secure if HTTPS is used even if this property is set to false.

boolean

false

Cookie path parameter value which, if set, will be used to set a path parameter for the session, state and post logout cookies. The cookie-path-header property, if set, will be checked first.

string

/

Cookie path header parameter value which, if set, identifies the incoming HTTP header whose value will be used to set a path parameter for the session, state and post logout cookies. If the header is missing then the cookie-path property will be checked.

string

Cookie domain parameter value which, if set, will be used for the session, state and post logout cookies.

string

If this property is set to 'true' then an OIDC UserInfo endpoint will be called

boolean

false

Session age extension in minutes. The user session age property is set to the value of the ID token life-span by default and the user will be redirected to the OIDC provider to re-authenticate once the session has expired. If this property is set to a non-zero value then the expired ID token can be refreshed before the session has expired. This property will be ignored if the token.refresh-expired property has not been enabled.

Duration

5M

If this property is set to 'true' then a normal 302 redirect response will be returned if the request was initiated via JavaScript API such as XMLHttpRequest or Fetch and the current user needs to be (re)authenticated which may not be desirable for Single Page Applications since it automatically following the redirect may not work given that OIDC authorization endpoints typically do not support CORS. If this property is set to false then a status code of '499' will be returned to allow the client to handle the redirect manually

boolean

true

Requires that ID token is available when the authorization code flow completes. In most case this property should be enabled. Disable this property only when you need to use the authorization code flow with OAuth2 providers.

boolean

true

Default TokenStateManager strategy.

keep-all-tokens, id-token, id-refresh-tokens

keep-all-tokens

Default TokenStateManager keeps all tokens (ID, access and refresh) returned in the authorization code grant response in a single session cookie by default. Enable this property to minimize a session cookie size

boolean

false

Allow caching the token introspection data. Note enabling this property does not enable the cache itself but only permits to cache the token introspection for a given tenant. If the default token cache can be used then please see OidcConfig.TokenCache how to enable it.

boolean

true

Allow caching the user info data. Note enabling this property does not enable the cache itself but only permits to cache the user info data for a given tenant. If the default token cache can be used then please see OidcConfig.TokenCache how to enable it.

boolean

true

Maximum number of cache entries. Set it to a positive value if the cache has to be enabled.

int

0

Maximum amount of time a given cache entry is valid for.

Duration

3M

Clean up timer interval. If this property is set then a timer will check and remove the stale entries periodically.

Additional properties which will be added as the query parameters to the authentication redirect URI.

Map<String,String>

Additional named tenants

Type

Default

The base URL of the OpenID Connect (OIDC) server, for example, https://host:port/auth. OIDC discovery endpoint will be called by default by appending a '.well-known/openid-configuration' path to this URL. Note if you work with Keycloak OIDC server, make sure the base URL is in the following format: https://host:port/auth/realms/{realm} where {realm} has to be replaced by the name of the Keycloak realm.

string

Enables OIDC discovery. If the discovery is disabled then the 'token-path' property must be configured.

boolean

true

Relative path of the OIDC token endpoint which issues access and refresh tokens using either 'client_credentials' or 'password' grants

string

The client-id of the application. Each application has a client-id that is used to identify the application

string

The maximum amount of time connecting to the currently unavailable OIDC server will be attempted for. The number of times the connection request will be repeated is calculated by dividing the value of this property by 2. For example, setting it to 20S will allow for requesting the connection up to 10 times with a 2 seconds delay between the retries. Note this property is only effective when the initial OIDC connection is created, for example, when requesting a well-known OIDC configuration. Use the 'connection-retry-count' property to support trying to re-establish an already available connection which may have been dropped.

Duration

The number of times an attempt to re-establish an already available connection will be repeated for. Note this property is different to the connection-delay property which is only effective during the initial OIDC connection creation. This property is used to try to recover the existing connection which may have been temporarily lost. For example, if a request to the OIDC token endpoint fails due to a connection exception then the request will be retried for a number of times configured by this property.

3

The amount of time after which the current OIDC connection request will time out.

Duration

10S

Relative path of the OIDC authorization endpoint which authenticates the users. This property must be set for the 'web-app' applications if OIDC discovery is disabled. This property will be ignored if the discovery is enabled.

string

Relative path of the OIDC userinfo endpoint. This property must only be set for the 'web-app' applications if OIDC discovery is disabled and 'authentication.user-info-required' property is enabled. This property will be ignored if the discovery is enabled.

string

Relative path of the OIDC RFC7662 introspection endpoint which can introspect both opaque and JWT tokens. This property must be set if OIDC discovery is disabled and 1) the opaque bearer access tokens have to be verified or 2) JWT tokens have to be verified while the cached JWK verification set with no matching JWK is being refreshed. This property will be ignored if the discovery is enabled.

string

string

Path to the claim containing an array of groups. It starts from the top level JWT JSON object and can contain multiple segments where each segment represents a JSON object name only, example: "realm/groups". Use double quotes with the namespace qualified claim names. This property can be used if a token has no 'groups' claim but has the groups set in a different claim.

string

Separator for splitting a string which may contain multiple group values. It will only be used if the "role-claim-path" property points to a custom claim whose value is a string. A single space will be used by default because the standard 'scope' claim may contain a space separated sequence.

string

Source of the principal roles.

idtoken, accesstoken, userinfo

Expected issuer 'iss' claim value. Note this property overrides the issuer property which may be set in OpenId Connect provider’s well-known configuration. If the iss claim value varies depending on the host/IP address or tenant id of the provider then you may skip the issuer verification by setting this property to 'any' but it should be done only when other options (such as configuring the provider to use the fixed iss claim value) are not possible.

string

Expected audience 'aud' claim value which may be a string or an array of strings.

list of string

string

Life span grace period in seconds. When checking token expiry, current time is allowed to be later than token expiration time by at most the configured number of seconds. When checking token issuance, current time is allowed to be sooner than token issue time by at most the configured number of seconds.

int

Name of the claim which contains a principal name. By default, the 'upn', 'preferred_username' and sub claims are checked.

string

Refresh expired ID tokens. If this property is enabled then a refresh token request will be performed if the ID token has expired and, if successful, the local session will be updated with the new set of tokens. Otherwise, the local session will be invalidated and the user redirected to the OpenID Provider to re-authenticate. In this case the user may not be challenged again if the OIDC provider session is still active. For this option be effective the authentication.session-age-extension property should also be set to a non-zero value since the refresh token is currently kept in the user session. This option is valid only when the application is of type ApplicationType#WEB_APP}.

boolean

false

Refresh token time skew in seconds. If this property is enabled then the configured number of seconds is added to the current time when checking whether the access token should be refreshed. If the sum is greater than this access token’s expiration time then a refresh is going to happen. This property will be ignored if the 'refresh-expired' property is not enabled.

Duration

Duration

10M

Custom HTTP header that contains a bearer token. This option is valid only when the application is of type ApplicationType#SERVICE}.

string

Allow the remote introspection of JWT tokens when no matching JWK key is available. Note this property is set to 'true' by default for backward-compatibility reasons and will be set to false instead in one of the next releases. Also note this property will be ignored if JWK endpoint URI is not available and introspecting the tokens is the only verification option.

boolean

true

Allow the remote introspection of the opaque tokens. Set this property to 'false' if only JWT tokens are expected.

boolean

true

The relative path of the logout endpoint at the application. If provided, the application is able to initiate the logout through this endpoint in conformance with the OpenID Connect RP-Initiated Logout specification.

string

Relative path of the application endpoint where the user should be redirected to after logging out from the OpenID Connect Provider. This endpoint URI must be properly registered at the OpenID Connect Provider as a valid redirect URI.

string

Relative path for calculating a "redirect_uri" query parameter. It has to start from a forward slash and will be appended to the request URI’s host and port. For example, if the current request URI is 'https://localhost:8080/service' then a 'redirect_uri' parameter will be set to 'https://localhost:8080/' if this property is set to '/' and be the same as the request URI if this property has not been configured. Note the original request URI will be restored after the user has authenticated if 'restorePathAfterRedirect' is set to 'true'.

string

If this property is set to 'true' then the original request URI which was used before the authentication will be restored after the user has been redirected back to the application. Note if redirectPath property is not set the the original request URI will be restored even if this property is disabled.

boolean

false

Remove the query parameters such as 'code' and 'state' set by the OIDC server on the redirect URI after the user has authenticated by redirecting a user to the same URI but without the query parameters.

boolean

true

Both ID and access tokens are fetched from the OIDC provider as part of the authorization code flow. ID token is always verified on every user request as the primary token which is used to represent the principal and extract the roles. Access token is not verified by default since it is meant to be propagated to the downstream services. The verification of the access token should be enabled if it is injected as a JWT token. Access tokens obtained as part of the code flow will always be verified if quarkus.oidc.roles.source property is set to accesstoken which means the authorization decision will be based on the roles extracted from the access token. Bearer access tokens are always verified.

boolean

false

Force 'https' as the 'redirect_uri' parameter scheme when running behind an SSL terminating reverse proxy. This property, if enabled, will also affect the logout post_logout_redirect_uri and the local redirect requests.

About the Duration format

The format for durations uses the standard java.time.Duration format. You can learn more about it in the Duration#parse() javadoc.

You can also provide duration values starting with a number. In this case, if the value consists only of a number, the converter treats the value as seconds. Otherwise, PT is implicitly prepended to the value to obtain a standard java.time.Duration format.
