[Samba] Unable to "show" a group using samba-tool

[David Kowis]

Howdy!

I'm setting up a domain controller, and things are going wonderfully, 
but I'm running into a strange problem, only some groups will display 
using the `samba-tool group show` command.

<snip>
root at vorador:~# samba-tool group addmembers videos dkowis
Added members to group videos
root at vorador:~# samba-tool group list | grep videos
videos
root at vorador:~# samba-tool group show videos
ERROR: Unable to find group "videos"
root at vorador:~# samba-tool user show dkowis | grep videos
memberOf: CN=videos,CN=Users,DC=dark,DC=kow,DC=is
</snip>

The group exists, I can add members to it, and those users show this 
membership.

I can only "show" some groups:

<snip>
root at vorador:~# samba-tool group list | egrep "Administrators|Domain 
Users"
Administrators
Domain Users
root at vorador:~# samba-tool group show "Administrators"
ERROR: Unable to find group "Administrators"
root at vorador:~# samba-tool group show "Domain Users"
dn: CN=Domain Users,CN=Users,DC=dark,DC=kow,DC=is
objectClass: top
objectClass: group
cn: Domain Users
description: All domain users
</snip>

I'm hoping someone here can help me understand why some groups show up 
using show, and some do not.
I'd really like to be able to see the group details, especially for the 
"videos" group, as it'll have GID and Unix details.

Thanks!
