[Samba] How to list members of a workgroup

[Jorgen Greve]

Hi
I look for a way to generate a text file, holding the workgroup/user
relation - which users belongs to a workgroup. Can I use a samba tool to
list all members of any known group? Or maybe run a domain ctlr, and
lookup the information in files on the server?
I must get this info from a M$ lan with arround 20.000 workstations and
some hudreds servers.
