RTC Client Single-Sign-On with Keberos/SPNEGO in CLM 6.0.0

All,

I am configuring CLM 6.0.0 applications for SSO. Browser is working with SSO. But I am not able to configure RTC Client to work with Kerberos/SPNEGO. It throws the following error:

"the following URL could not be reached because your Kerberos/SPNEGO ticket is not valid or has expired: /ccm/service/com.ibm.team.repository.common.internal.IRepositoryRemoteService.
  CRJAZ2901E The following URL could not be reached because your Kerberos/SPNEGO ticket is not valid or has expired: /ccm/service/com.ibm.team.repository.common.internal.IRepositoryRemoteService. "

I am following IBM documentation.

Please share your thought.

Thanks,

Pradeep
