If you encounter this error on the SP:

Request Entity Too Large
The requested resource
/testapp
does not allow request data with GET requests, or the amount of data provided in the request exceeds the capacity limit. 

Set the ShibExportAssertion^? off in your Apache config on the SP

If you insist that you'd like the data to be going through, you can also enable the following:

1. in apache's config, put LimitRequestFieldsize 65536
2. in workers.properties, put worker.xxx.max_packet_size=65536 where xxx is your worker name
3. in ajp connector (tomcat server.xml), put packetSize="65536" (e.g. <Connector="8009"... packetSize="65536" ...> )
