[SSSD-users] Tickets with and without REALM

[Peter Tulpen]

Hello everyone
I see a strange behaviour in the ticket listing of my users:

I always have a ticket with the REALM and without the realm. This could fit to other problem I have like nonworking kerberos login via ssh and access issues.

Any ideas where this could come from?

my klist output:
