Good job there. I tested various scenarios (2 master, fallback with SRV
records, old client (RHEL 6.2)) and most worked for me, but only I
worked under the root account. This is what I got with non-root:

$ ipa user-show admin
...
ipa: DEBUG: stderr=
ipa: DEBUG: args=keyctl search @s user ipa_session_cookie
ipa: DEBUG: stdout=113632397

ipa: DEBUG: stderr=
ipa: DEBUG: args=keyctl pupdate 113632397
ipa: DEBUG: stdout=
ipa: DEBUG: stderr=keyctl_update: Permission denied
ipa: INFO: trying https://vm-131.idm.lab.bos.redhat.com/ipa/session/xml
ipa: DEBUG: NSSConnection init vm-131.idm.lab.bos.redhat.com
ipa: ERROR: cannot connect to 'any of the configured servers': ...

Shouldn't we use @us instead of @s for storing user session keys?


Secondly, I wonder if we also plan to add some logout command? This way
even if I do kdestroy, the session still exist and someone other may
still execute commands.
