I had a look at the pam_krb5 source and it seems to generate standard prompt (like the ones we regression test for).
If you have this could you please attach /var/log/lightdm/lightdm.log and /var/log/lightdm/x-0-greeter.log after this occurs (it will show some information about what messages were sent between the daemon and the greeter). Also could someone give steps to set up the simplest Kereberos environment to reproduce this. Thanks. ** Changed in: lightdm (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/972537 Title: lightdm doesn't allow expired passwords To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/972537/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
