[cvsnt] Switch to user failed due to configuration error

[sanjeev taria]

Hello!

When I try to connect to a remote repository through a client machine  
(through :pserver:user <at> localhost:/root):

Fatal error, aborting.
cvs [login aborted]: cvsuser: Switch to user failed due to configuration 
error
Contact your System Administrator.

My config is set to systemauth=no and the user is mapped to a real user 
'cvsuser' which has all rights on the repository. Changing the 
systemauth setting doesn't help. I am on win XP pro.and my server is on win 
server 2003

Can any body help me out how to solve this problem
Thanks in advance,

Sanjeev Taria
