> Master should not deactivate an authenticated framework/slave upon receiving a new AuthenticateMessage unless new authentication succeeds. As it stands now, a malicious user could spoof the pid of an authenticated framework/slave and send an AuthenticateMessage to knock a valid framework/slave off the authenticated list, forcing the valid framework/slave to re-authenticate and re-register. This could be used in a DoS attack.
> But how should we handle the scenario when the actual authenticated framework/slave sends an AuthenticateMessage that fails authentication?
