I have installed gnats 3.113.1 and gnatsweb 2.8.2 in a server. now i have
done with instaalation.. i could able to send and edit PR from web. but the
problem is how to configure it.

1. i gnatsd.access i have a username and passwd for a user with accessleve
and dbase alias name.  now when a user creates a PR his reporters mail id
field is filled by him and he can give any email id. how to restrict this
stuff. is there any possiblity of having unix username and passwd
associated with gnatsd.access user name and passwd.

2. once logged in thru web from a browser froma machine the last login
remains even if we kill the browser. so once logged in the cookies get
enables. how to make it to ask every time for username and passwd.

I am in very much need of this help. gnatsweb users kindly help me to solve
the above mentioned problems.
