| Choose Y here if you want to allow other computers to access |

| You may choose to use a user-space NFS server instead, in which |
| case you can choose N here. |
| |
| To export local file systems using NFS, you also need to install |

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