Subject RE: OT RE: Still having problem retrieving user value from ISAPI Filter for authentication

Thanks Leo.  I've got the same setup in IIS regarding integrated windows security.  However,
IIS is on port 80 and Tomcat is on 9080 so as not to conflict.

IIS is giving the ISAPI filter the user info that I'm looking for as indicated in the ISAPI

Thanks for trying.  It's appreciated.

I stand corrected, as usual.  Snoop JSP does display my login info.  However, my browser is
now set to supply credentials for internal sites.  "Automatic login only in Intranet zone".
