If you add Shibboleth or alternate SSO to Richard's recipe you will at least reduce the need for a reauth. though the session will still be lost.

we have the following set up for our production environment:
* Single Oracle Database instance with failover instance (on another site, data replicated with I believe DataGuard)
* Two Tomcats (on separate sites), with Apache in front (using mod_jk)
* (Hardware) Load balancer with sticky session set
We do no session clustering of any sort, just let the load balancer session stick to a tomcat instance. We find that's good enough for most cases, if the tomcat goes down then the session will be lost and user will have to log in again on the other server.
One of the tomcat servers is also used for also running grouper hook and any automation imports we use (although I like Colin's deployment where the automation tasks are split off into a dedicated server :)).

Subject: [grouper-users] HA-ing grouper ...
We're currently looking at piloting Grouper and the question has been raised about the possibility of a high availability (HA) deployment. The database
and sources (LDAP in this case) are both HA. Assuming a load-balancer is front-ending Grouper, that just leaves tomcat. Tomcat has clustering recipes - anyone tried/thought-about-trying such a configuration for Grouper? Any thoughts on why this might be a bad idea? Would clustering actually be necessary?
