APEX

I am having a problem with the session that I get from ASP.NET and APEX accepting it. I am on an APEX 3.2.1 version. I do not have access to anything other than developing PL/SQL with inthe APEX app, so setting server variables, etc is out of the question (NTLM authentication not available as an option). The issue I have to work around it this: the current APEX server is being decommissioned and the new server is not getting the rights to talk to the SSO server. We have access to SSO through an ASP.NET web server. I need to be able to send the SID (login id) from the SSO session info in ASP.NET to APEX. I have reviewed a lot of the discussions inthe forum and unfortunately I have run into a problem with the sessionid. The sessionid I get from ASP.NET is alphanumeric (http://xxxxx.xxxxx.xxxxx:7777/pls/apex/f?p=30003:1:*w1rh3x55axuefhedrycel545-10834564*) and is much longer than the typical sessionid from APEX and returns a 404 error when used. How do I go about modifying the session id to have it work with APEX. I do not have access to WWV_FLOW_SESSIONS$ to be able to determine what is required for setting the appropriate cookie either.

Any help is appreciated.

Thanks
