[Samba] Usiing SID's in Linux? Is it possible?

[Jeff Sadowski]

I would like to be able to use SID's in linux so as to have ACL's identical
to windows.
Example usage why:

Say I have an ntfs partitioned disk that I share with a co-worker that uses
windows.

Currently I am connected to the domain using rfc2307 and that allows me to
authenticate using AD and on the nfs through the Isilon the windows users
see files correctly permissioned but when I share an ntfs partitioned disk
the ACL's are not correct.
