This can also cause some serious other problems. Don't know why you want to do this, but here's a solution. (Using LDAP backend would make this spiffy, but this should be ok) On the server where stuff actually rights, share that as an NFS share and mount it on the "Gateway" server. Then share the nfs mount point via samba. The LDAP part comes in because you can have both servers using ldap for users and groups and keep your permissions and UID/GID stuff global. > I > can make sure the user accounts line up on the two servers, that's no > big > deal.
