Thanks for your help!
I also did 'new' installation on laptop (where user already existed). During that
installation i noticed few warnings that may or maynot be related:
No SRV records of NTP servers found and no NTP server or pool address was provided.
WARNING: The configuration pre-client installation is not managed by authselect and cannot
be backed up. Uninstallation may not be able to revert to the original state.
Unable to find 'admin' user with 'getent passwd admin(a)home.mydomain.com'!
Unable to reliably detect configuration. Check NSS setup manually.
Here is a copy of straced ssh and sssd_mydomain.log:
