OT: fas-username vs. local username for fedora-cvs

[Josephine Tannhäuser]

Hi all!

My username on my private pc is josephine, my username on my
workstation is josephine.tannhauser, but my fas-username is tannhauser.

how can I use fedora-cvs on these machines? It seems that fedora-cvs
want to use the local username. How can I change this behavior with
editing a configfile in my home-dir? I don't want to edit the 
fedora-cvs package-files.

Currently i have a alternate user on my private pc, but this is not a
good solution. :-)
