Using Mod_Proxy to connect Apache/Httpd to Tomcat

Steps

1. assumed you've enabled mod_proxy on your apache/httpd
2. edit appropriate vhost file to mount tomcat application to httpd

         ProxyRequests Off
         <Proxy *>
            Order deny,allow
            Allow from all
         </Proxy>
         ProxyPass /shibboleth-idp ajp://localhost:8009/shibboleth-idp
   

3. The above assumes you've enabled ajp at tomcat on port 8009, you can use other mode such as http://localhost:8080/shibboleth-idp
4. edit $TOMCAT_HOME/conf/server.xml and make sure this entry exists

     <Connector port="8009" enableLookups="false" 
         request.tomcatAuthentication="false" tomcatAuthentication="false"
         redirectPort="8443" protocol="AJP/1.3" />
