- The problem is that LOGINOUT, when invoked by RLOGIN to login a
- user without checking the password, also bypasses these other checks.
- We do some of them ourselves (eg, checking for logins completely
- disabled), but don't want to try to get into the business of tracking
- every change that DEC makes to LOGINOUT. When DEC provides a callable
- interface to LOGINOUT which lets us do this, we'll use it. In the
- mean time, if you need the login limit enforcement, you'll need to
- disable RLOGIN.
