Also consider following points when doing SSO : 
* make sure that LDAP is same on Portal and Connections and make sure that the Realm name is exactly the same 
* make sure that both servers are accessed through a common domain like .yourwebsite.com 
* just export LTPA from one server to another and you should be set 
* just make sure that in the Web SSO settings for each server the domain name is the same, and put a period in front of it 
* ex: .yourwebsite.com 
* one last thing, make sure the time and time zones are the same on both servers 
* otherwise you could generate a cookie that has already expired on the next server
