Comment 3 for bug 1586707

In fact the problem is solved using the "winbind expand groups" parameter in /etc/samba/smb.conf with the value of 1 (winbind expand groups = 1) .

This was the default in earlier versions of samba, and was changed to 0 (winbind expand groups = 0) from version 4.2.x.

I appreciate the contribution !
