Comment 15 for bug 1254619

After talking to Adam Young, I still don't see any utility in splitting REMOTE_USER and discarding half the value. We do agree that it should be fixed in master & havana to match grizzly's behavior of using the entire REMOTE_USER value as a username in the default domain.

So, I'd like to fix this bug in the open but I do think it makes sense to issue an OSSN regarding the potential risk in attempting to use Havana's broken behavior. I'd also like to piggyback the OSSN email asking for deployer feedback on the fix itself, before it merges.
