49 Solaris NFS servers support an auxiliary NFSv3 ACL protocol that
50 never became an official part of the NFS version 3 protocol.
51 This protocol extension allows applications on NFS clients to
52 manipulate POSIX Access Control Lists on files residing on NFS
53 servers. NFS servers enforce POSIX ACLs on local files whether
54 this protocol is available or not.

60 access and modify ACLs on your NFS server.
