in this case, same user on windows and unix, would the following not be the best approach?
set vol permissions style as ntfs, then create an /etc/usermap.cfg to map unix to windows user?
we do this in a limited scenario for some applications so that the users can manipulate data from their windows workstations but the unix application server sees all those files and can access them as the correct uid/gid
just a thought.

What you are seeking to do, is do-able however...if you're seeking to fulfill a requirement that both NFS and CIFS clients have access...you can still do this with either NTFS or UNIX style security. Can be NTFS security for an NFS client, or UNIX security and gain access from CIFS client.
Do a search on NOW for "multiprotocol access" or somesuch...should find tons of docs.
Without mixed mode, clients will get the ACL that is there...if UNIX style security, CIFS clients can access resources as long as they're allowed according to the ACL. Similarly, NFS clients access NTFS style security resources. You just need to get your usermapping correctly...CIFS clients must map to a UNIX user and vice-versa - depending on which protocol you decide on.
All mixed mode buys you is the ability to "set ACL's from either client", assuming they have rights to do so. Once you set the ACL in mixed mode, the ACL is either NTFS or UNIX and not "translated" to the client. The ACL will always be whatever the last client set it as, like tmac said.
G'luck!

The big problem is still there...
the last one to set permissions wins...
i.e. CIFS ACL wipes NFS perms NFS perms wipes CIFS ACLs

I know that "back in the day" there where some good reasons not to use mixed mode qtrees if at all possible. We've got folks accessing their home directories via NFS and CIFS depending on which of their workstations they are using so it would be very nice if I could use mixed mode. Is it realistic to do this in a production environment? What
are the drawbacks?
