I've followed the steps on http://us4.samba.org/samba/docs/man/winbind.html for setting up winbind. I was able to add my machine to the domain as specified using smbpasswd (though I did not do it using the AD tool on Windows, do I need to?), the smbpasswd cmd said it joined successfully. I verified that the machine account was created on the AD. I then restarted smb, and started winbind. When I do a wbinfo -u I get "Error looking up domain users" If I do a wbinfo -p it pings winbind successfully. So I reckon there's something wrong. I'm using RH 7.2, with the samba-2.2.5 RPM from the samba website. The global section of my smb.conf is below. Could someone give me a hint to what's going on?
