Force asp.net mvc website on IIS to ask for usercredentials in a intranet environment

[JuergenW71]

Hi,
for a single website on our iis 10 intranet server we have the requirement to force the user to enter his windows credentials (again) . how can i achive this.

i tried to send http 401 in session_start. it shows the login screen, but if the user press cancel, the website uses the user credentials from the windows login, and this should avoided.

the website use asp.net mvc 5 with c#. 

all other websites on this server use the integrated windows authentication, but for this special on this is not allowed by internal auditing

Thanks

I believe, you should configure IIS to use Basic Authentication for your web site. Go to Authentication option in IIS configuration, enable Basic Authentication and disable other methods.
