What are Keycloak s OAuth2 OpenID Connect endpoints

Question

We are trying to evaluate Keycloak as an SSO solution  and it looks good in many respects  but the documentation is painfully lacking in the basics   For a given Keycloak installation on http   localhost 8080  for realm test  what are the OAuth2 Authorization Endpoint  OAuth2 Token Endpoint and OpenID Connect UserInfo Endpoint    We are not interested in using Keycloak s own client library  we want to use standard OAuth2   OpenID Connect client libraries  as the client applications using the keycloak server will be written in a wide range of languages  PHP  Ruby  Node  Java  C   Angular   Therefore the examples that use the Keycloak client aren t of use for us

After much digging around we were able to scrape the info more or less  mainly from Keycloak s own JS client lib     Authorization Endpoint   auth realms  realm  tokens login Token Endpoint   auth realms  realm  tokens access codes   As for OpenID Connect UserInfo  right now  1 1 0 Final  Keycloak doesn t implement this endpoint  so it is not fully OpenID Connect compliant  However  there is already a patch that adds that as of this writing should be included in 1 2 x   But - Ironically Keycloak does send back an id token in together with the access token  Both the id token and the access token are signed JWTs  and the keys of the token are OpenID Connect s keys  i e    iss      realm    sub     5bf30443-0cf7-4d31-b204-efd11a432659   name    Amir Abiri   email          So while Keycloak 1 1 x is not fully OpenID Connect compliant  it does  speak  in OpenID Connect language

With version 1 9 3 Final  Keycloak has a number of OpenID endpoints available  These can be found at  auth realms  realm   well-known openid-configuration  Assuming your realm is named demo  that endpoint will produce a JSON response similar to this        issuer    http   localhost 8080 auth realms demo      authorization endpoint    http   localhost 8080 auth realms demo protocol openid-connect auth      token endpoint    http   localhost 8080 auth realms demo protocol openid-connect token      token introspection endpoint    http   localhost 8080 auth realms demo protocol openid-connect token introspect      userinfo endpoint    http   localhost 8080 auth realms demo protocol openid-connect userinfo      end session endpoint    http   localhost 8080 auth realms demo protocol openid-connect logout      jwks uri    http   localhost 8080 auth realms demo protocol openid-connect certs      grant types supported          authorization code        implicit        refresh token        password        client credentials          response types supported          code        none        id token        token        id token token        code id token        code token        code id token token          subject types supported          public          id token signing alg values supported          RS256          response modes supported          query        fragment        form post          registration endpoint    http   localhost 8080 auth realms demo clients-registrations openid-connect      As far as I have found  these endpoints implement the Oauth 2 0 spec

For Keycloak 1 2 the above information can be retrieved via the url     http   keycloakhost keycloakport auth realms  realm   well-known openid-configuration   For example  if the realm name is demo      http   keycloakhost keycloakport auth realms demo  well-known openid-configuration   An example output from above url          issuer    http   localhost 8080 auth realms demo        authorization endpoint    http   localhost 8080 auth realms demo protocol openid-connect auth        token endpoint    http   localhost 8080 auth realms demo protocol openid-connect token        userinfo endpoint    http   localhost 8080 auth realms demo protocol openid-connect userinfo        end session endpoint    http   localhost 8080 auth realms demo protocol openid-connect logout        jwks uri    http   localhost 8080 auth realms demo protocol openid-connect certs        grant types supported              authorization code            refresh token            password              response types supported              code              subject types supported              public              id token signing alg values supported              RS256              response modes supported              query            Found information at https   issues jboss org browse KEYCLOAK-571  Note  You might need to add your client to the Valid Redirect URI list
