Windows Authentication Scheme Prerequisites

In order to use the Windows Authentication scheme, the following prerequisites must be met:

• For legacy WinNT directories or Active Directory in mixed mode:
  • The user directory connection you create in the Policy Server User Interface must specify the WinNT namespace.
  • The requested resources can be located on any type of web server, but the authentication server and the Web Agent protecting those resources must be on a Microsoft IIS web server.
• For Active Directories running in native mode:
  • User data must reside in an Active Directory.
  • User directory connections must specify either an LDAP or AD namespace.
  • The requested resources can be located on any type of web server, but the authentication server and the Web Agent protecting those resources must be on a Microsoft IIS web server.
  • Client and server accounts must be enabled for delegation.
• Users must log in using Internet Explorer Web browsers (4.0 or later).
• To work on IIS6 in Windows 2003, the Verified that file exists option in the Wildcard Application Maps must not be set.
• Windows Authentication schemes also require that any virtual directory on the IIS web server that contains the creds.ntc file remain unprotected.
• Internet Explorer browser options must be setup to allow automatic logon with a user’s current username and password.
