---------------------------------------------------------

@Harsh, Thanks for comming up with Fix . But here are my questions

1) As per the fix you are using the List of GID's sent by NFS Client to NFS Proxy.  But in
this approach are disadvantages like 1) max of 16 GID/ UNIX ID 2) Requires integration of
Client machine with LDAP and its a big pain. 

2) Why the List of GID for each UID is not retrieved from OS/LDAP instead of list of List
of GID's sent by NFS Client to NFS Proxy. Doing so it will eliminate the need for Client machines
to integrate with LDAP.
