This is a terribly useful feature update for those of us who work in mixed AD/NFS environments that depend on unix netgroups. Previously, mapping of permissions using groups didn't work because of the LDAP based primacy which meant that groups had the same name, but MS have now improved server to natively support netgroups, which indicates an improvement to the previous problem where if the group names matched, Windows couldn't natively use the NFS group. I'll be testing this on Friday with my boss, who is the lead Unix analyst, and will post back if results are promising. It means an end to using 3rd party tools to share out unix groups, thus causing grief when unsupported file structures are created on an NTFS filesystem . . .
