How to invoke a Report directly

Hello,

we've recently upgraded our Forms/Reports infrastructure from 10g to 12c. We now use OAM/OID instead of OSSO/OID.

But we can no longer invoke a Report directly. It fails with:

REP-56071: A security check failed with error message User does not exist in Id Store

If I open forms or simply showjobs in another tab, I get the OAM cookie and the reports then works as expected.

It seems to me that Reports should forward unauthenticated requests to OAM.

Is there a way to configure this?

Thanks,

Gabriel.
