Part of the problem was good old fashioned chmod's. Although I can't
tell which was the culprit, making the home dir, the .ssh dir, and the
authorized_keys2 file itself to 755, I can redo the procedure below for
UNIX login CVS on the server box. (That's good because the procedure
below causes the repository entries to be owned by root which would
hose up other users and CVS itself.) I suspect any login will work.
Also, I don't think SELinux is a problem in this thread.
