I'm having trouble using an AD group as a 'valid users = @DOMAIN+group' in my samba share definition. I have a Windows SBS 2003 w/SP1 ADS/PDC and a Fedora Core 4 system running a 3.0.14a-2 samba. All updates applied. When I do DOMAIN+user it works fine. When I do as above, It fails (I get the pw box). I have verified that I am a member of the group I am testing with. I see some messages in the logs (below). What do they mean and what should I do to get access to shares by an AD group?
