cvs [server aborted]: you are unknown to this system

[Martin Ellison]

The message "cvs [server aborted]: you are unknown to this system"
occurs if a cvs user tries to do a commit and the cvs userid is not a
valid login on the server (using pserver).

What is the best option to get around this (other than getting the
user an account on the server)? Part of the idea of pserver is to
allow a user to use CVS without a server account.

There is an #ifdef in the code that is intended to stop commits as
root -- should I just disable this? (and what is the best way to do
so? a parameter to ./configure?)
