I am very new to mod_proxy. Gone thru some tutorials and configured mod_proxy. Everything works great except this issue. Couldn't solve even after spending hrs in googling. Issue is - I have apache in front of tomcat (running in port 8080) in my internet website. I am using mod_proxy to mask the port 8080.
I have configured a tomcat instance with SPNEGO to perform user authentication. When I access the tomcat port directly, it causes my browser to request my user name and password, which I provide and which it validates correctly.
So far I haven't persuaded it to do the silent SPNEGO/Kerberos handshake and authenticate me without needing to type credentials, but that's another issue.
