 - After installing and configuring Oracle Webgate for IIS 8.5 - unable to access the IIS server. The sequence that occurs is:
  a) HTTP Request to the IIS Server
  b) Redirect to OAM
  c) Authentication at OAM
  d) Redirected to IIS server
  e) OAMAuthnCookie set by webgate
  d) HTTP 500 error code received

The intial traffic between the webgate and OAM appears to be working. The user is forwarded to OAM for authentication then sent back to the webgate. obrar.cgi on the webgate side successfully sets a valid OAMAuthnCookie.

x509 Authentication is configured and working properly.
There are no exceptions or errors recorded in the Event Viewer
