Microsoft applications such as Internet Explorer and IIS do not use
the MIT libraries at all.  Therefore, none of the MIT tools will be
involved in the discussion.

Assuming that Internet Explorer is forwarding the credential to IIS,
the only way the credential can be used is by requesting impersonation
within the IIS thread which kicks off the CGI.  The MIT GSSAPI libraries
will not be involved in this.

A better forum to ask your question might be the newsgroup.
