LDN - Luminis Developer Network

We are getting ready to convert our DBs to Oracle 11g on Nov 11 weekend and they just sprung on me that we are going with an Oracle SCAN listener on the DB cluster. I checked with SunGard and they say that Luminis 4 has not been tested using SCAN connections. I changed the LMG settings and it looks like it is connecting properly to the Banner DB but I can not seem to get the Luminis DB connection set up properly. When I try and log in, I get past the login screen but I get uPortal errors and nothing is rendered. Is anybody using SCAN and did they encounter any issues with it?
