OpenID Connect Support

Since Payara Server 4.1.2.183 and 5.183

The Payara API provides a @OpenIdAuthenticationDefinition annotation that creates an authorization mechanism for OpenID Connect support. This works in the same way as other authorization mechanisms in the Java EE Security API.

Usage

The OpenID Connect authentication mechanism is defined through the @OpenIdAuthenticationDefinition annotation. Specifying this in a valid place as defined by the Java EE Security API will create the mechanism. Often this may mean that any class is a valid position.

Example

Here’s an example that configures a OpenID Connect client:

@OpenIdAuthenticationDefinition(
       providerURI = "https://sample-openid-server.com",
       clientId = "87068hgfg5675htfv6mrucov57bknst.apps.sample.com",
       clientSecret = "{my-secret}",
       redirectURI = "${baseURL}/callback",
       extraParameters = {
            "testKey=testValue",
            "testKey2=testValue2"
       }
)
public class SecurityBean {

}

See this sample project for a more detailed example.

When defining a OpenID Connect flow within an application deployed on Payara Server, it is possible to retrieve the access token, identity token, user claims and the other authentication information within any bean in the scope of the callback/redirectURI resource used to configure the authentication:

@WebServlet("/callback")
public class CallbackServlet extends HttpServlet {

    @Inject
    OpenIdContext context;

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        PrintWriter out = response.getWriter();
        //Here's the caller name
        out.println(context.getCallerName());
        //Here's the caller groups
        out.println(context.getCallerGroups());
        //Here's the unique subject identifier within the issuer
        out.println(context.getSubject());
        //Here's the access token
        out.println(context.getAccessToken());
        //Here's the identity token
        out.println(context.getIdentityToken());
        //Here's the user claims
        out.println(context.getClaimsJson());
    }
}

Configuration

OpenID Client can be configured with both @OpenIdAuthenticationDefinition annotation attributes and Microprofile Config properties. The annotation and MicroProfile properties has several configuration options.

They are detailed below.

Table 1. Configuration Options
Option	MP Config property	Required	Description	Default value	Requirements
`providerURI`	`payara.security.openid.providerURI`	true	The provider uri to discover the metadata of the OpenID Connect provider.		The endpoint must be HTTPS.

`extraParameters`		false	An array of extra options to be sent to the OpenID Connect provider.		Must be in the form `"key=value"`.

Note : If both an annotation attribute and a MicroProfile Config property are defined for the same option then the MicroProfile Config property value always takes precedence over the @OpenIdAuthenticationDefinition annotation value.

Expression Language Support

Additionally, the @OpenIdAuthenticationDefinition supports the use of expression language (EL) notation for dynamic configuration scenarios. This means that you can use any CDI bean properties to set the OpenID Connect configuration like this:

@OpenIdAuthenticationDefinition(
    providerURI="#{openidConfigBean.tokenEndpointURL}",
    clientId="#{openidConfigBean.clientId}",
    clientSecret="#{openidConfigBean.clientSecret}",
    redirectURI="#{openidConfigBean.redirectURI}"
)
public class SecurityBean {
}

Client Secret Aliasing

The client secret can be input directly, or for added security it can be aliased using any of the following features:

Fetch Caller Data

As OpenId Connect Client is built on top of Jakarta EE Security API, therefore javax.security.enterprise.SecurityContext interface can provide caller info which is available as a CDI bean and can be injected into any context-aware instance.

The Payara API also provides a fish.payara.security.openid.api.OpenIdContext interface which is also available as a CDI bean and consist of the following methods:

The getCallerName() method - Gets the caller name of the currently authenticated user.
The getCallerGroups() method - Gets the groups associated with the caller.
The getSubject() method - Subject Identifier. A locally unique and never reassigned identifier within the Issuer for the End-User, which is intended to be consumed by the Client.
The getTokenType() method - Gets the token type value. The value MUST be Bearer or another token_type value that the Client has negotiated with the Authorization Server.
The getAccessToken() method - Gets the authorization token that was received from the OpenId Connect provider.
The getIdentityToken() method - Gets the identity token that was received from the OpenId Connect provider.
The getRefreshToken() method - Returns the refresh token that is used by OIDC client to get a new access token.
The getExpiresIn() method - Return the time that the access token is granted for, if it is set to expire.
The getClaimsJson() method - Gets the User Claims JSON that was received from the userinfo endpoint.
The getClaims() method - Gets the User Claims that were received from the userinfo endpoint.
The getProviderMetadata() method - The OpenId Connect Provider’s metadata document fetched via provider URI.

Google integration

The Payara API provides the in-built support for Google OpenID Provider via the @GoogleAuthenticationDefinition annotation.

Request Refresh Token

To enable the refresh token feature, set the tokenAutoRefresh to true and add the access_type parameter value to offline so that application can refresh access tokens when the user is not present at the browser.

If application requests offline access then the application can receive access and refresh token. Once the application has a refresh token, it can obtain a new access token at any time or as older ones expire. Otherwise, If application requests online access, your application will only receive an access token

@GoogleAuthenticationDefinition(
    providerURI="#{openidConfigBean.tokenEndpointURL}",
    clientId="#{openidConfigBean.clientId}",
    clientSecret="#{openidConfigBean.clientSecret}",
    ...
    tokenAutoRefresh = true,
    extraParameters = {"access_type=offline", "approval_prompt=force"}
)
public class SecurityBean {
}

Azure AD integration

The Payara API also provides the in-built support for Azure AD OpenID Provider via the @AzureAuthenticationDefinition annotation.

Request Refresh Token

To receive the refresh token, set the tokenAutoRefresh to true and explicitly add the offline_access scope to the definition.

@AzureAuthenticationDefinition(
    providerURI="#{openidConfigBean.tokenEndpointURL}",
    clientId="#{openidConfigBean.clientId}",
    clientSecret="#{openidConfigBean.clientSecret}",
    ...
    tokenAutoRefresh = true,
    scope = {OPENID_SCOPE, EMAIL_SCOPE, PROFILE_SCOPE, OFFLINE_ACCESS_SCOPE}
)
public class SecurityBean {
}

Groups mapping

To add the groups to the registered application, Sign in to the Azure portal > Azure Active Directory > Manage > App registrations > select your application: image::security-connector/oidc/azure/app_registrations.png[Select application]
You may also add the custom roles via Roles and administrators under the Manage section: image::security-connector/oidc/azure/custom_role.png[Add Custom Roles]
Now to map group claims, select Token configuration under the Manage section: image::security-connector/oidc/azure/token_configuration.png[Token configuration]
Press Add groups claim button to select group types and customize Id and/or Access token properties: image::security-connector/oidc/azure/add_groups_claim.png[Add Groups Claim]
Groups claim can also be defined via Azure Manifest under the Manage section which is a JSON configuration file.
To retrieve and map the caller name & groups from token claims, set the caller name & group claim definition to preferred_username & groups.

@AzureAuthenticationDefinition(
    providerURI="#{openidConfigBean.tokenEndpointURL}",
    clientId="#{openidConfigBean.clientId}",
    clientSecret="#{openidConfigBean.clientSecret}",
    ...
    claimsDefinition = @ClaimsDefinition(
            callerGroupsClaim = "groups",
            callerNameClaim = "preferred_username"
    )
)
public class SecurityBean {
}

Keycloak integration

Keycloak is Open Source Identity and Access Management Server, which is a OAuth2 and OpenID Connect(OIDC) protocol complaint. In this section, the basic steps are described to setup Keycloak OpenId provider.For more details about Keycloak configuration options, please visit to the official documentation: https://www.keycloak.org/documentation.html

Refer Keycloak getting started documentation to run and setup keycloak.
After Keycloak setup done, login to Keycloak admin console and add the new realm by pressing the Add Realm button: image::security-connector/oidc/keycloak/add_realm.png[Add Realm]
Copy the OpenId endpoint configuration URL from endpoint section: image::security-connector/oidc/keycloak/realm_endpoint.png[Realm Endpoint]
Now add the Role that will be used by the application to define which users will be authorized to access the application. image::security-connector/oidc/keycloak/add-role.png[Add role]
Create the Groups: image::security-connector/oidc/keycloak/create-group.png[Create Groups]
Add the User: image::security-connector/oidc/keycloak/add-user.png[Add User]
After the user is created, set a new password for the user: image::security-connector/oidc/keycloak/set-user-password.png[Set Password]
Now map the user to roles. Click on Role Mappings tab and assign the roles to the user from the available roles: image::security-connector/oidc/keycloak/user-role-mapping.png[User Role Mapping]
Assign the user to the groups. Click on Groups tab and join the groups from the available groups: image::security-connector/oidc/keycloak/join-group.png[Join Groups]
Create the OpenId Client by clicking the Client option from sidebar and press the create button: image::security-connector/oidc/keycloak/create-client.png[Create OpenID Client] Enter the Client ID and select the Client Protocol openid-connect and press Save.
After the openid client is created change its Access Type to confidential and enter the valid Redirect URIs: image::security-connector/oidc/keycloak/client-access-type-confidentail.png[Access Type]
Next copy the client secret from Credentials tab. image::security-connector/oidc/keycloak/client-secret.png[Client Secret]

Here’s an example that configures a OpenID Connect client for Keycloak provider. To test the KeyCloak OpenId provider, enter the copied Client Secret, Client ID (client name) and the endpoint configuration URL:

@OpenIdAuthenticationDefinition(
    providerURI = "http://${keycloak-host}:${keycloak-port}/auth/realms/test-realm",
    clientId = "test-client",
    clientSecret = "1f6744ae-d7e7-4876-bc44-78fb691316a1"
    ...
)
public class SecurityBean {
}

Groups mapping

To get the groups details in token claims, navigate to Keycloak admin console > OpenId Client > Mappers tab > press create button > Select Group Membership mapper type > enter the Name and Token Claim Name > press Save. image::security-connector/oidc/keycloak/groups-claim.png[Groups Claim]
To retrieve and map the caller name & groups from token claims, set the caller name & group claim definition to preferred_username & groups.

@OpenIdAuthenticationDefinition(
    providerURI = "http://${keycloak-host}:${keycloak-port}/auth/realms/test-realm",
    clientId = "test-client",
    clientSecret = "1f6744ae-d7e7-4876-bc44-78fb691316a1"
    ...
    claimsDefinition = @ClaimsDefinition(
            callerGroupsClaim = "groups",
            callerNameClaim = "preferred_username"
    )
)
public class SecurityBean {
}
