RHEL4 and and above use CIFS, rather than SMB.  I can execute this:
# mount -t cifs -o credentials=/etc/samba/ad.cred //fs1/home /mnt

But then the contents of the mount are all owned by root.  I can chown
and chgrp on a user's directory in the CIFS-mounted share, and I see on
the Linux client that ownership has changed.  The permissions on the
home directory are reported as mode 777; but as root I cannot access the
contents of that user's home directory.

Are the specific mount.cifs options you might recommend?
