I am running in an environment here where it is mandatory that I run SSO 10g (the old verison 10.1.x.x OAS based). How do I go about enabling SSO in APEX 4.2.1? Can I use the same ssosdk902.zip I used with APEX 3.x.x or do I need a different one? There is no plans to go to upgrade off of our legacy 10g SSO or go to OAM based SSO. I would appreciate any information that can be offered.
