Hi everyone,

After upgrading (using rpm, yum upgrade) I can no longer login to my
machines using ssh. Before the upgrade everything was working fine.

Some loose facts:
- I'm installing IPA packages from the RHEL repositories onto RHEL systems,
so I'm not sure if this is the right mailing list to ask for assistance
- I have a basic setup of IPA with minimum rules (deleted HBAC rules to
single that out), using SSSD+PAM.
- Both other machines that are upgraded to a more recent version of sssd
and it's fellow packages and servers which was not yum upgraded are
affected by the issue, thus, everything seems to point at IPA.
- I'm able to obtain a kerberos ticket via kinit
- Running the following package version: ipa-server-4.1.0-18.el7.x86_64

SSH returns (adding -vvv hardly tells me anything useful):
Connection closed by UNKNOWN

I think that I have boiled down the issue to the following..
Both clients with upgraded sssd (1.12.2-58) and non upgraded clients
(1.11.2-65) give me the following output in sssd_<domain>.log:
(Mon Mar 16 14:12:17 2015) [sssd[be[domain.com]]] [hbac_eval_user_element]

I'm happy to attach more logs if needed.
I would very much like to avoid rolling back to an older IPA version by
reinstalling everything from scratch.
Any and all help would be very much appreciated.

Thanks in advance,
Andreas
