cvs access denied (write permission)

[josef radinger <cheese nosuchhost net>]

since several days i'm trying to update some spec-files via cvs and i
seem not to able to do that.

after some fiddling i found that i had to upload a new rsa-key (i tried
with dsa and got no meaningfull errormessage). i even managed to update
~fedora.cert + friends, but still no luck (the logmessage has only my
own comment for updateing):

[rpmbuild cheese teg]$ cvs commit 
cvs commit: Examining .
cvs commit: Examining F-7
cvs commit: Examining F-8
cvs commit: Examining F-9

? F-9/teg-0.11.2-16.fc9.src.rpm
cvs [server aborted]: "commit" requires write access to the repository
cvs commit: saving log message in /tmp/cvsmCWfVR


any ideas?

yours
