49	help
50	  Solaris NFS servers support an auxiliary NFSv3 ACL protocol that
51	  never became an official part of the NFS version 3 protocol.
52	  This protocol extension allows applications on NFS clients to
53	  manipulate POSIX Access Control Lists on files residing on NFS
54	  servers.  NFS servers enforce POSIX ACLs on local files whether
55	  this protocol is available or not.
56
57	  This option enables support in your system's NFS server for the
58	  NFSv3 ACL protocol extension allowing NFS clients to manipulate
59	  POSIX ACLs on files exported by your system's NFS server.  NFS
60	  clients which support the Solaris NFSv3 ACL protocol can then
61	  access and modify ACLs on your NFS server.
62
63	  To store ACLs on your NFS server, you also need to enable ACL-
64	  related CONFIG options for your local file systems of choice.
