[Samba] AD Domain member not authenticating

[Edward Wissner]

I have been following this thread.  I have a similar configuration to John
with the same problem.  I am running Mandrake 10.1 Community.  I have
installed the latest krb5-1.3.X package from MIT.  I am trying to authorize
users using a w2k AD server.
One question (possibly silly), why does every example smb.conf file use '+'
as the winbind separator?  If the defualt is '\' , why not leave it at that?
I am able to authenticate to the serve, see the shared directories, but
cannot authenticate to the directory.  If I create a Unix/Samba user, that
user can use the shared directories.

I'm still searching for a solution.
