Hello,

I'm using Keycloak for the first time, so sorry if this is a newbie question.

When I use keycloak, oauth scope attribute is never present in keycloak tokenEndpoint responses and in introspect responses.

From the specs, it scope attribute should be present when calling token and tokenIntrospect endpoint, but it's never returned by keycloak endpoints :

 * token endpoint response - see [2] for a sample
   from https://tools.ietf.org/html/rfc6749#section-5.1

   <quote>scope OPTIONAL, if identical to the scope requested by the client; otherwise, REQUIRED</quote>

 * token introspection see [3] for a sample
   from https://tools.ietf.org/html/rfc7662#section-2.2

      scopes associated with this token, in the format described in
      Section 3.3 of OAuth 2.0 [RFC6749].</quote>

   Oups... optional in the spec ??? what's the introspection use then ???

I know I can key roles from keycloak JWT AT (in realm_access.roles for instance), but it's not in OAuth specs and I would like to stick with the standard.

Am I doing something wrong ?

I'm using Keycloak with a Spring Boot application (using Spring OAuth library - I know there's a Spring keycloak adapter, but since my application uses others OIDC / OAuth provider I would like to stick with Spring OAuth), and since no scope attribute is present in the responses, I've receive no scope in my application.

I've tested with a sample role hello.say.

I created a realm role of the same name, and assigned it to me test user.

I've made sure my application request this scope during authorization request.

Here's my spring configuration (requesting a hello.say scope), more exactly :

spring:
  profiles: keycloak
security:
  oidc:
    client:
      expectedIssuer: http://localhost:8180/auth/realms/demo
      keyUri: http://localhost:8180/auth/realms/demo/protocol/openid-connect/certs
  oauth2:
    client:
      clientId: sample-resource-server
      clientSecret: 55175ff5-23d4-487c-a572-67d9715ea765
      scope: openid refreshToken hello.say
      access-token-uri: http://localhost:8181/auth/realms/demo/protocol/openid-connect/token
      user-authorization-uri: http://localhost:8181/auth/realms/demo/protocol/openid-connect/auth
    resource:
      serviceId: ${PREFIX:}resource
      tokenInfoUri: http://localhost:8181/auth/realms/demo/protocol/openid-connect/token/introspect

Really sorry for the long mail

Thanks for the help !

Adrian
