Comment 19 for bug 1781418

I don't know why this happens, but seems to be something broken by the way and update didn't fix anything in my case. There are still 2 calls to 'setgroups(0, NULL)', one for libpam-kwallet and another for pam_kwallet5 after my user and group are already set. Of course, this drops all supplementary groups. Maybe I miss something. The only workaround is commenting out both libraries in lightdm config.

But this is only some workaround, no final fix! Would be fine needed changes to be made in corresponding modules and after that... everything done.
