Cross Instance Authentication Issues

Question

I have the portal meta-data installed and running on an instance called DMD1 and all of our users are on a different instance called DCD1. Prior to this setup our metadata and client data was on the same instance and I would run a PSP with the ...pls/portal/schema.package.procedure.
With this setup (meta-data in one instance and client data in another) I get ie-404 errors. Can anyone direct me to a resource that would explain the configuration changes that I would have to make in order to allow PSP's on DCD1 to be available through the portal on DMD1?
I have created a DAD on the DMD1 instance with a specific USERNAME and PWD and can use that DAD to execute a PSP on DCD1 but I need each user to run the PSP as themselves.
Any assistance or resources that will provide an explanation of SSO in this type of environment will be appreciated.
Thank you,
Mark Johnson

Basically I can now say "f*ck you adobe. I as a college
student who likes to host things on my 150 MB of server space can
no longer host XML formatted levels for games I write. Because I am
not the administrator of the server and will never be able to
convince the administrator to let me have the MCDP file allow my
flash file to load it's levels."
F*ck you Adobe, F*ck You.
