[keycloak-user] Kerberos token

I am trying to hook up APIMan with KeyCloak using Kerberos and OAuth2. I am trying to get a token from key cloak using the following URL: curl -X POST http://localhost:29080/auth/realms/freeipa/protocol/openid-connect/token -H "Content-Type: application/x-www-form-urlencoded" -d "username=admin" -d 'password=Secret123' -d 'grant_type=password' -d 'client_id=mapper' -d 'client_secret=027fbd51-135b-47d6-86cd-7ce541b38984' But, get an exception back: 2016-05-23 14:22:25,676 DEBUG [org.keycloak.services] (default task-51) AUTHENTICATE CLIENT 2016-05-23 14:22:25,676 TRACE [org.keycloak.services] (default task-51) Using executions for client authentication: [de08b32a-a4a5-469c-91cc-0fbca51e1c2f, de3db156-dcc2-4346-bf3a-e56e8e10ed5f] 2016-05-23 14:22:25,676 DEBUG [org.keycloak.services] (default task-51) client authenticator: client-secret 2016-05-23 14:22:25,676 DEBUG [org.keycloak.services] (default task-51) client authenticator SUCCESS: client-secret 2016-05-23 14:22:25,676 DEBUG [org.keycloak.services] (default task-51) Client mapper authenticated by client-secret 2016-05-23 14:22:25,676 TRACE [org.keycloak.models.sessions.infinispan.InfinispanUserSessionProvider] (default task-51) Adding cache operation: ADD on 7ad60b45-4e69-45a4-a995-ee65d9ee47ae 2016-05-23 14:22:25,676 TRACE [org.keycloak.models.sessions.infinispan.InfinispanUserSessionProvider] (default task-51) Adding cache operation: REPLACE on 7ad60b45-4e69-45a4-a995-ee65d9ee47ae 2016-05-23 14:22:25,676 TRACE [org.keycloak.models.sessions.infinispan.InfinispanUserSessionProvider] (default task-51) Adding cache operation: REPLACE on 7ad60b45-4e69-45a4-a995-ee65d9ee47ae 2016-05-23 14:22:25,676 TRACE [org.keycloak.models.sessions.infinispan.InfinispanUserSessionProvider] (default task-51) Adding cache operation: REPLACE on 7ad60b45-4e69-45a4-a995-ee65d9ee47ae 2016-05-23 14:22:25,676 TRACE [org.keycloak.models.sessions.infinispan.InfinispanUserSessionProvider] (default task-51) Adding cache operation: REPLACE on 7ad60b45-4e69-45a4-a995-ee65d9ee47ae 2016-05-23 14:22:25,676 TRACE [org.keycloak.models.sessions.infinispan.InfinispanUserSessionProvider] (default task-51) Adding cache operation: REPLACE on 7ad60b45-4e69-45a4-a995-ee65d9ee47ae 2016-05-23 14:22:25,676 DEBUG [org.keycloak.services] (default task-51) AUTHENTICATE ONLY 2016-05-23 14:22:25,676 TRACE [org.keycloak.models.sessions.infinispan.InfinispanUserSessionProvider] (default task-51) Adding cache operation: REPLACE on 7ad60b45-4e69-45a4-a995-ee65d9ee47ae 2016-05-23 14:22:25,676 DEBUG [org.keycloak.services] (default task-51) processFlow 2016-05-23 14:22:25,676 DEBUG [org.keycloak.services] (default task-51) check execution: direct-grant-validate-username requirement: REQUIRED 2016-05-23 14:22:25,676 DEBUG [org.keycloak.services] (default task-51) authenticator: direct-grant-validate-username 2016-05-23 14:22:25,676 DEBUG [org.keycloak.services] (default task-51) invoke authenticator.authenticate 2016-05-23 14:22:25,676 TRACE [org.keycloak.models.sessions.infinispan.InfinispanUserSessionProvider] (default task-51) Adding cache operation: REPLACE on 7ad60b45-4e69-45a4-a995-ee65d9ee47ae 2016-05-23 14:22:25,677 TRACE [org.keycloak.federation.ldap.idm.store.ldap.LDAPIdentityStore] (default task-51) Using filter for LDAP search: (&(uid=admin)(objectclass=person)) .
