When I try to commit some files on cvs server, I take the following error:

cvs commit -m "no message" ContainerPUC.cs (in directory
C:\Local-GrASP-CVS\instantiation_location\EU-GrASP\src\GrASP\Container\Conta
inerPUC\)
cvs commit: Empty password used - try 'cvs login' with a real password

cvs [commit aborted]: authorization failed: server cvs.rus.uni-stuttgart.de
rejected access to /usr/cvsroot/Grasp for user crmpa_rovezzi

But, I am not the user crmpa_rovezzi.

How I can resolve this problem?

thanks in advance
