Subject Tomcat 5.5.23 SingleSignOn Thread-safe?
Date Wed, 07 Nov 2007 05:34:38 GMT


I'm using Tomcat 5.5.23 with SSO enabled. I also implemented a customer
Realm (extending RealmBase).

It's been working great but just recently I've noticed that some session
mix-up happening under high load.

I am at loss to find where/why this happened. I looked at my own Realm
implementation, but authenticate() method is called only once when user
first authenticates himself. Subsequent calls does not invoke authenticate()
method in my customer Realm, so it must be handled somewhere else in Tomcat


Can anybody point me to a right direction, please?
