Can you provide me a complete set of logs from both machines? The one where
pam_sss_gss.so is working fine and the problematic one?
I will take a look at them and will try to figure out what the issue is.
You can send it to me directly at ppolawsk(a)redhat.com.

If I run 'klist' at this point, I can see that I've picked up tickets for
krb5tgt/IPA.EXAMPLE.NET(a)EXAMPLE.NET and host/
myself.ipa.example.net(a)IPA.EXAMPLE.NET; so I think the PAM module is
working, but sssd_pam doesn't like what it sends and closes the connection
