Bug#756458: gdm3: When logging in, pam_group.so does not add user to group according to /etc/security/group.conf via pam_group.so

[Nye Liu]

Package: gdm3
Version: 3.12.2-2
Severity: normal

Dear Maintainer,

   * What led up to the situation?

Upgraded to latest gdm3

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Add gdm and gdm3 to /etc/security/group.conf:
  gdm;*;*;Al0000-2400;audio, video, cdrom, floppy
  gdm3;*;*;Al0000-2400;audio, video, cdrom, floppy

Add pam_group.so to /etc/pam.d/common-auth:
  auth    optional        pam_group.so

Login via gdm3 to an xsession

   * What was the outcome of this action?

Not added to "audio, video, cdrom, floppy" groups.

   * What outcome did you expect instead?

Expected to be added to above groups.

Worked fine in a much older version of gdm3 (not sure which one)
