I added a gid to two different groups within the AD/OU. This does fix the -1 GIDs, as evidenced by the replacement of one of the -1's with GIDs 2002 and 2003 for the two different groups, one for each user:
For the same user as shown above (see the appearance of the 2003): user@Host:~$ wbinfo -r user 2001 -1 2003 10000 -1 -1 100002 100001 For an alternate user who had 2003 appear in place of the -1: user@Host:~$ wbinfo -r user2 2001 -1 2002 100002 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1307778 Title: getent group on trusty returns only local groups To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1307778/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
