Not sure what you mean by server-config.

But the /usr/afs/KeyFile on the servers only have des keys and key
version numbers. It can not check which key belongs to
which principal. So as long as the kvno's are different on
the principals for afs/cellname@OUR.DOMAIN and afs@OUR.DOAMIN
you can add both keys to the KeyFile.
