Subject RE: Single Sign-On problems

The only reason I think it's Tomcat because when we change the Tomcat version it seems to
affect the speed of the application (Tomcat 7 runs very slow, but no SSO errors; Tomcat 6
runs fast, but SSO errors). We're using Active Directory to authenticate. I guess it could
be SSL as well. I've change the domain controller, but that didn't affect the issue. Here
is the code we changed in the conf\web.xml file:
    <!-- ** needs reviewed to avoid domain Preauth check

Would you mind specifying which SSO mechanism you are using where, and why you believe
that the problem is related to Tomcat ?
