Single sign-on in Resin 3x

Does Resin 3x support single sign-on?  Resin 2x support it by configuring the 
<login-config> within the <http-server> node.  It seems Resin 3x only allows 
the <login-config> to be in <web-app-defaul> or <web-app> nodes and thus there 
isn't single sign-on for all applications deployed in the same server and/or 
host.
 
Am I missisng something??
 
 
Thanks,
