We have an Oracle Access Manager 11g R2PS2 (OAM WebGate 10g on IIS 7.5, 32bits. It is connected to OAM 11g R2 PS2 and it works well.

This WebGate has an authorization policy that sets a couple of headers, including the IMPERSONATE header. To test, I have created a page that dumps all of them and we see that the IMPERSONATE header is set.
When we enable the Impersonator Module, the same request is authenticated as usual, but when the page is displayed we get an error 500. I have two other environments configured the same way that have impersonation working.
