Really could use some help with Single Sign on

I have watched the videos and followed all the instructions I have found. But SSO seems to now want to play along.

It would help if I could find logs that gave me a clue where to start.

So far the Spark logs and openfire logs are no help. Any help on where to start troubleshooting would be greatly appreciated.

I am running a w2k12 domain with RHEL clients that authenticate via Kerberos. My clients and other applications work just find. Spark is fighting me and I have run out of ideas.

Thanks in advance for any advice

Tom
