> For each SSO entry, their should be child node per server where the SSO has been used.  This is different from the current where all the session data for an SSO is in one node. The data map in each child node would hold the session ids of the sessions active on that server.
> This kind of structure avoids most lock contention between different servers.
> Can't do this in 4.0.x as it prevents interoperation with earlier releases.
