ASP NT Authentication

[olaf]

I'm currently developing an intranet site. My problem is how to authenticate
a user from an ASP page to the NT Domain conrtoller without using the NT
login popup? I know IIS requires the NT login popup to be populated by the
user, is there a way for an ASP page to apss the username and password then
IIS will authenticate with the domain controller???


Many thanks
Olaf

if you switch of basic authentication, and anonymous, leaving only NTFS - IE
will do "passthrough" authentication of the logged in NT user.

Take a look in the help files for ASP on authentication.

"Dialog Box Free" version of IIS authentication called also
NT Challenge or (NTLM in some docs) is the default
authentication method of IIS.

User credentials are validated by handshake mechanism without
prompting for user name and password. But this mechanism has also certain
drawbacks when acceesing resources on other machines than IIS server (for
example remote SQL with NT Authentication). This is due to the lack of DELEGATION
on NT Platform.
