[keycloak-user] HTTP 403 Forbidden on Keycloak.getInstance

Hi, I have a realm with an application called : examples-admin-client <http://localhost:8080/auth/admin/master/console/#/realms/cv/applications/... and would like to use it to manage my realm but i get an error : javax.ws.rs.ClientErrorException: HTTP 403 Forbidden every time i make the following call : Keycloak keycloak = Keycloak.getInstance(authServer, "realm-name", "User1", "password", "examples-admin-client", "a5890cdf-e1df-40c0-9d50-26ad2f7badde"); When i try to do the same thing with the example realm (i use the json example-realm.json provided by the keycloak project) this works nicely actually ! Btw, i can successfully login with the user : User1 with that password. This is the json for my realm : { "realm": "realm-name", "realm-public-key": "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCxwUIE6W3BZYlSxDPpwkknb2ObnrEsGMUJGy3HfNEfkfu9rcY5bxkllLsW32KlR78++xtuI11IE2nuh6nJmUsIKMb55Ez9n7/E9kPmSF6lxavZlQY0HfBnR3ZWgzsoUUz4n7pOhmqHIAGXeuxnMDQ5/upwcolFIZRor1v7oT/H8QIDAQAB", "auth-server-url": "http://localhost:8080/auth", "ssl-required": "none", "resource": "examples-admin-client", "credentials": { "secret": "a5890cdf-e1df-40c0-9d50-26ad2f7badde" } } Thanks for any help on this one !
