The NFS service supports Kerberos Version 5 authentication, integrity, and privacy when you configure NFS clients and servers to support Kerberos. You can use the mount and share command-line options when you use Kerberos for secure authentication. For information about Kerberos Version 5 authentication, see Configuring Kerberos NFS Servers in Managing Kerberos and Other Authentication Services in Oracle Solaris 11.2 .
