Thanks,

Adding '-Dhttps.protocols=TLSv1' to tomcat startup didn't disable SSLv3 
(openssl.exe s_client -connect HOSTNAME:443 -ssl3 still successfully 
connects). I am using a load balancer but it is configured as an SSL 
Bridge in this case so that all SSL traffic gets passed through to the 
backend hosts. I have a similar setup with Shibboleth and the Tomcat 
change works without issue there.

Thanks Again,
Aaron
