Windows Server 2012 R2
Internet Explorer 11
I have an IIS web application that supports Windows Authentication (Providers: Negotiate, NTLM).
I have a use case where a given user has multiple accounts. His IE settings consider the site to be "local intranet" zone and as such, automatically attempt to logon with the username he's logged in Windows with. He needs to use his other account to properly authenticate with the site but doesn't get a challenge prompt to enter the credential. When this happens, the site immediately returns a 403 error and that's it.
Is there a way to configure the IIS site to challenge the user to authenticate instead of give up? I can't remove the site address from the "Local Intranet" Zone in his browser due to security policies and likewise, I can't change the automatic logon policy for the entire Local Intranet Zone.
Is there another way?
