[Samba] how does one edit a domain group

[Linda Walsh]

After I mapped a local group to a domain group, I'm not longer able
edit it with 'net sam'.

Is there another tool I should use?  How do I add users on other
computers, in the domain to the group?

I don't see a tool on a client station for allowing editing of
domain groups....??

I tried a NT4-compat remote domain management tool, but it just
crashed when I tried to connect it to samba...(oops/sigh)...
