We are integrating Oracle WebCenter portal 11g with Oracle Access Manager 11g and also setting up SSO for all the applications (i.e. WebCenter, Content Server, Portlets and SOA). In our environment we have WebCenter and SOA in different servers. As of now we have a WebGate 11g in WebCenter Portal server with OHS. We don't have any WebGate in SOA Server. We are following WebCenter 11g (22.214.171.124.0) Admin Guide. In order to setup SSO among these apps (WebCenter, Content Server, Portlets and SOA), is it required to install WebGate in SOA Server as well? as we have SOA and WebCenter in 2 different servers. Please clarify on this if anyone has implemented SSO.
