#2060 Cached credentials aren't working with sssd-ad UPN logins
Closed: Fixed None Opened 5 years ago by jhrozek.

Ticket was cloned from Red Hat Bugzilla (product Fedora): Bug 1001310

Description of problem:

Using SSSD AD and a UPN username login (i.e where the UPN name doesn't equal
the domain name) succeeds correctly when connected to the network. However the
user in unable to login when offline. Cached credentials aren't working.

Version-Release number of selected component (if applicable):
sssd-1.11.0-0.1.beta2.fc19.x86_64

How reproducible:
Everytime

Steps to Reproduce:
1.Login whilst connected to the network
2.Logout
3.Disconnect network cable
4.Attempt to login when off the network

Actual results:
Unable to login off the network

Expected results:
Login succeeds off the network

Additional info:

I can't guarantee this is due to UPN logins, but I'm guessing due to presumably
cached credentials working for users on simpler domains. I have no way of
testing this.

My very un-sssd expert eyes seem to indicate that sssd is losing the username
(lots of name "(unknown)" appearing) somewhere in the process.
