A lot of good replies.
The problem that I’ve been running into is that if someone access a file
via Windows any Unix users have problems with chmod.
I can’t use Unix
perms because there are places where I need more granularity then it permits. It
looks like I’ll just have to maintain a separate location for my

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
