[CentOS] CentOS 5.4 x86_64 authenticating against AD (Server 2008r2)

>Wbinfo -u & wbinfo -g do indeed work for me however getent passwd or getent group returns no AD users or groups. I have winbind entries in nsswitch for both the passwd & >group entries. Josepeh, I will try a newer RPM from a different repository and see if that resolves my issues. Did my smb.conf look ok?

getent doesn't need to return data for this to work, just wbinfo.
It's likely the issue I spoke of, aside from the winbind entries
in smb.conf that allow local logon.

Take my advice:
yum erase samba == uber happiness

Get ldap working, no interop issues with the old samba version in rhel and
newer ms servers. Plus you will be using something forward compatible that
a txt edit could likely fix in the event something drastic changed in the
schema and search filters for example had to change.
