|  | Choose Y here to enable Secure RPC using the Kerberos version 5 | 
|  | GSS-API mechanism (RFC 1964). | 
|  |  | 
|  | Secure RPC calls with Kerberos require an auxiliary user-space | 
|  | daemon which may be found in the Linux nfs-utils package | 
|  | available from http://linux-nfs.org/.  In addition, user-space | 
|  | Kerberos support should be installed. |
