We have been using a Kerberos authentication component in IIS to authenticate users against the campus Kerberos realm from our web site. It was developed by the computer lab and/or UM staff, and I believe this is the same thing HR is using for the attendance system. I am trying to move the web site to a Windows 2000 box, but I am having troubles registering the kerberos.dll (probably because Win2K has it's own kerberos.dll which provides totally separate functionality). Has anyone been able to get this component working on Windows 2000? Are there other options available for doing Kerberos authentication via the web?
