If you are a member of a domain with a huge number of groups, you can
take a short cut to figure out what mkgroup-l-d is really looking for.

I did this:

depriest@quagmire ~
$ ls -n -l
total 40
-rw-------    1 43363    10513        8591 Feb 17 12:47 .bash_history

depriest@quagmire ~
$ mkgroup -d | grep 10513
Domain Users:S-1-5-21-1718497100-374411357-7473742-513:10513:
depriest@quagmire ~
$ 

The '-n' lists the user names and groups as their GID/UID number.  I
then used mkgroup to list all the domain groups and grep'd for the GID
listed.
Problem solved.  It was looking for Domain Users.
I can just put that entry in my /etc/group file and all is good now.

See:

depriest@quagmire ~
$ ls -l
total 40
-rw-------    1 depriest users_d      8591 Feb 17 12:47 .bash_history
-rwxr-xr-x    1 depriest users_d       533 Dec 10 17:48 .bash_profile*
-rwxr-xr-x    1 depriest users_d       625 Dec 10 17:48 .bashrc*
drwxr-xr-x+   4 depriest users_d      4096 Jan  8 18:02 .cpan/
-rwxr-xr-x    1 depriest users_d       267 Dec 10 17:48 .inputrc*
drwx------+   2 depriest users_d         0 Dec 23 11:34 .links/
drwxr-xr-x+   2 depriest users_d         0 Dec 15 13:07 .ncftp/
drwx------+   2 depriest users_d      4096 Jan  8 14:20 .ssh/
-rw-------    1 depriest users_d      6020 Feb  9 15:04 .viminfo
-rwxr-xr-x    1 depriest users_d       205 Dec 15 13:17 .wgetrc*
depriest@quagmire ~
$ 

I changed the display name of the group from 'Domain Users' to 'users_d'
in my /etc/group file so it would fit in the column better.
