can't commit! permissions question

[Schwenk, Jeanie]

Who is supposed to be the owner of the files that are in the respository?  I
can update and checkout but not commit.  Obviously the permissions are wrong
somewhere.  I've been looking in the OpenSourceDevelopment with CVS by Fogel
and in the Cederqvist but I must conclude I've just not run across the
needed info or it's not there.  

The accounts on the unix box are cvsadmin,sc, and jschwenk.  The files in
the repository are owned by sc but I'm logged in as cvsadmin.  I imported a
new directory of files as user jschwenk.  I just checked in the repository
and those files are owned by jschwenk.  Does that mean that no one but
jschwenk can commit these files?  How do other individuals ever
checkout/commit then?  How can permissions be controlled?  Does one need to
give files a different user before checking in?

Here's the passwd file. 

anonymous:!:
cvsadmin:6Ji:
dkennedy:Jul:sc
pkuah:Jul:sc
jschwenk:Jul:cvsadmin

As cvsadmin, I can't commit the changes that were sent to me from the
contractors because I don't have proper permissions.  

If any of this is unclear, please email me directly cause I need help!
