Hi Dudes, I have a samba Version 3.0.23d that has successfully joined our Server 2003 ADS domain. # wbinfo -u shows the users # wbinfo -g shows the groups And I can chown/grp directories to NT users & groups. However, # net groupmap list only shows Administrators (S-1-5-32-544) -> BUILTIN\administrators Users (S-1-5-32-545) -> BUILTIN\users So if I try to map groups, this is what happens. # net groupmap modify ntgroup="Domain Admins" unixgroup=domadmins # NT Group Domain Admins doesn't exist in mapping DB One other problem. I get permission denied when I try to Modify ACLs. The ext3 file system is mounted with acl and nt acl support = yes is in the share section defined. Please help with a hint. I have Googled and read the Samba Chapter 12/13 on the net command to no avail. Thanks. Craig
