Regarding NFS server username/password authentication

Hi;
I had set up NFS server in one ubuntu box and mounted few directories using it.
In order to access those directories across the network i m using j-ftp(an open source java network client) from other boxes in the same network.I am able to view my mounted directories in the server through it.
I want to know if there is a way in NFS server where by i can provide username/password authentication so that only authorized users will be able to view my mount share in NFS server.I searched the api of j-ftp client where i found "pcnfsd" may prove useful for it but i am not able to find any thing on that regarding NFS server authentication from client for Ubuntu.

following is the login method in the api of j-ftp:

com.sun.nfs
Class XFileExtensionAccessor

public boolean loginPCNFSD(String host,
String username,
String password)
Sets the user's RPC credential from Login name and password. Every NFS request includes a "credential" that identifies the user. An AUTH_SYS credential includes the user's UID and GID values. These are determined from the user's login name (and password) by the PCNFSD service that must be available on a local server. Once the credential is set, it is assigned globally to all future NFS XFile objects.
If this method is not called, a default credential is assigned with a UID and GID of "nobody".

Parameters:
Returns:
true if the login succeeded, false otherwise.

Please help me if der is ne way to provide an authentication from NFS server in Ubuntu box for which i will be very thankful.

Thanks in advance;
Ajay

mountd

mountd(1M)																mountd(1M)

NAME

       mountd - server for NFS mount requests and NFS access checks

SYNOPSIS

       /usr/lib/nfs/mountd [-v] [-r]

       mountd  is  an  RPC  server  that  answers  requests  for  NFS  access  information  and  file  system  mount  requests.  It reads the file
       /etc/dfs/sharetab to determine which file systems are available for mounting by which remote machines. See sharetab(4). nfsd running on the
       local  server  will  contact mountd the first time an NFS client tries to access the file system to determine whether the client should get
       read-write, read-only, or no access. This access can be dependent on the security mode used in the remoted procedure call from the  client.
       See share_nfs(1M).

       The command also provides information as to what file systems are mounted by which clients. This information can be printed using the show-
       mount(1M) command.

       The mountd daemon is automatically invoked by share(1M).

       Only super user can run the mountd daemon.

       The options shown below are supported for NVSv2/v3 clients. They are not supported for Solaris NFSv4 clients.

       -r	Reject mount requests from clients. Clients that have file systems mounted will not be affected.

       -v	Run the command in verbose mode. Each time mountd determines what access a client should get, it will log the result to  the  con-
		sole, as well as how it got that result.

       /etc/dfs/sharetab       shared file system table

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWnfssu 		   |
       +-----------------------------+-----------------------------+

       nfsd(1M), share(1M), share_nfs(1M), showmount(1M), nfs(4), sharetab(4), attributes(5)

       Since  mountd  must  be	running for nfsd to function properly, mountd is automatically started by the svc:/network/nfs/server service. See
       nfs(4).

       Some routines that compare hostnames use case-sensitive string comparisons; some do not. If an incoming request fails, verify that the case
       of the hostname in the file to be parsed matches the case of the hostname called for, and attempt the request again.
