[Bug 302092] Re: logging in immediately logs out again

[lagoinsomne]

I noticed this behaviour after this  two events: some days ago I shared
a directory with samba. Everything went fine, except that having two
networks I just couldn't see the shared directory in another windows
machine, but that is another problem.

Today I installed a new printer and connected to 127.0.0.1:631 (cups),
and after that I could not sudo, so rebooted the computer. After reboot
I couldn't login, so I restarted in recovery mode and then I realized
that three files in /var/lib/samba had changed this day, so I renamed
them and voilá, I could login again.

The three files that were changed today were:
/var/lib/share_info.tdb
/var/lib/secrets.tdb
/var/lib/passwd.tdb

After login in successfully I checked /var/lib/samba and sectrets.tdb
and passdb.tdb were recreated and the md5sum is different from the old
ones. Share_info.tdb was not recreated, and seeing the date it seems
that registry.tdb and ntprinters.tdb were touched or recreated again.

This bug is nasty because you just can't login, and if that happens to
someone without another computer to check the solution then is hard to
fix it.
