Best practice for CAS load balance/failover

[Bin Rong]

Hi all,

I am a newbie to CAS, and in our production environment, we have two apahche
servers running behind a hardware load balancer, using ajp to balance
out to several tomcat instances. Sticky session is used, and only one of the
backend tomcat is used for CAS.

Now we want to load balance/failover CAS, the options are:

1. Clustering CAS
2. Have database-backed registry, so that multiple CAS can validate the
ticket vended by other CAS servers.

Just wondering what is the best practise?

We think the database-backed is a good one, and I've searched the web, there
is very little information in this regard, except
http://www.ja-sig.org/wiki/display/CASUM/Clustering+CAS. Could anyone point
to any source of information or any detailed howto guide?

Any advise is appreciated.

Bin
