I am not an expert in WAS and would like to know if there is something extra that needs to be done to achieve Single Sign on between products in CLM 2012.  Right now when a user logs into RRC (or any of the other CLM products), they need to log in.  And when they navigate to one of the other products, they are prompted to log in again.  The Websphere instance is version 8.0.0.4 and there is only a single application server on the instance.  All three products (RRC, RTC, RQM) are deployed, along with JTS and the other standards.  All of the articles I've looked at assume that each product is deployed on a separate instance of WAS, or a different profile, and walk you through sharing tokens and copying it that way.

We have virtual hosts setup for each product and are using Websphere's web server.  Is there something special you need to do in Websphere still to enable Single Sign On?  Can you still achieve Single Sign On if deployed on a single instance of WAS?

If anyone can point me to a specific article on this, or let me know if it can be done, I'd appreciate it.

Thanks
