login & password

I use Microsoft Information Server 3.0 (Windows NT4.0+NTFS).
I have some folders not for everyone. So when I get access to this restricted folders I need to enter login & password.
In one of my web pages in this folder I have a form which has CGI as an action. The question is: Can I use this login & password in my CGI script? How can I do it? I use Borland C++ 5.0. I suppose that I can get login from "REMOTE_USER"
environment variable. But what about password?

I don't have the answer to this question, but I have seen several queries similar to yours.

UNIX uses the .htaccess method which does not map over onto NT, as I understand it any equivalent method on NT requires an NT type login account. The REMOTE_USER does not work on NT as it does on UNIX.

Remote user doesn't work with most browsers.

For Philippe: that's not right Remote_user will be available on most unix hosts after the user logs in(as required by .htaccess). You are prabably thinking of http_from which was designed to give the users email address.(don't worry most browsers don't use this)
for sto: Why would you need the password?  They have already been authenticated by the system.  If they are accessing your script, they have access, and you can use remote_user to see who it is(if you have more than one user).  If you don't have more than one user don't bother checking it at all.
I don't know about NT; icd might be right about remote_user not working.  There may be some other way to find out who has logged in.

For n3mtr: My script works with Interbase database so I need password for Interbase authentication.

sto - that's only a small idea:

Have a look at the WindowsNT IIS helpfiles, because some w3 servers need special naming of the cgi. (WebSite do so, a cgi, which should get the username and password have to start with a "$").

If WindowsNT and IIS doesn't gave you any possibility to get the password, generate one with the username and a string stored in the cgi. - I do this on my WindowsNT IIS 3.0 machine, because I didn't find out how to get the password.

By the way, I'm programmin with Borland Delphi 2.x and I wrote a component supporting the CGI interface - it's free.

you can't get the password, because the password is encrypted
in one direction.  You need to store the password somewhere
that you can retrieve it based on the userid, which you can get
from the REMOTE_USER environment variable.  The REMOTE_USER
variable is available on all browsers that can go to a page with authentication.  In otherwords, if you can't get the REMOTE_USER variable, they can't see your page, so it doesn't matter.  I use
a database table with the user and password stored in it.
