configure GNATS and GNATSWeb to have login

[Shibo Zheng]

Hi all,

I have just installed GNATS 4.0 - beta1 and GNATSWeb 3.99.3. Two problems
and help is wanted.

1. I have modified files, submitters(with passwords), responsible etc for
the database "default", there is no password option from the HTML login form
when using GNATSWeb from IE explorer. How to enable it?
It is not Authentication against the WWW server. 
2. Another thing is that any user (type anything into the user name text
box) can login from GNATSWeb, create / query PRs. Access control has no
effect.

Many thanks,

Shibo
