Thanks for replying! It was nsswitch.conf ! I had previously (about 3 weeks ago) modified nsswitch.conf to something like this passwd: compat winbind shadow: compat group: compat winbind and I could login all the time without problems. Somehow, after updating the system to latest kernel an dbus versions, it started to play the foul ... As soon as I put passwd: files compat winbind shadow: files compat group: files compat winbind and restarted the system, I could login as root or whatever I wanted. It's weird, though ...
