[Samba] Windows Administrator Rights

[Thomas Harvey]

HI all, I hope this is a simple one...

I have machines joined to a Samba domain and all users authenticate and logon with roaming profiles just fine. Excellent. When doing windows administration tasks, installing software, changing settings, I need to authenticate as an admin user. Currently, I need to enter the local admin user and password. This is becoming a bit of a bind, can I have a centrally stored (in the LDAP with everyone else) admin user. I have tried the Domain Admin samba group to no avail, I guess I want a Windows admin as opposed to a Domain admin.

Any help?

Thanks
