Andre, I haven't tried your full suggestion yet, but I removed all of the OAM SSO stuff out of my Apache httpd.conf, just to see what happens, but even after that, still am not getting logged into Tomcat, so it may be as you suggest, that mod_jk tries to get the userid from somewhere deep inside of Apache. So, I will try adding what you suggested, to get authenticated with just the Apache, and then see what happens, and will post back. If that works, we can go from there. Thanks for following up with this!
