CVS problems

[Rodrigo Moya <rmoya tsai es>]

Hi all!

I am having problems with a newly created CVS account. I call cvs with
'login' and no error is reported, so then I make a 'checkout' and I get
the following error:

sheinze: no such user

What's wrong? I know the user has been added by Miguel, so I don't know
what's happening

Thanks
