Thread: ASP NT Authentication

    ASP NT Authentication


    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

    Re: ASP NT Authentication

    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.

    Re: ASP NT 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.
