Advanced Secure Gateway Software - ASG ProxySG Software - SGOS


There may be a requirement to have the authenticated user information displayed in the HTTP header (for example if the upstream device needs to know user details for accounting purposes).


There is no pre-defined function for this on the ProxySG/ASG, however you can enable this header using CPL code or through VPM.

Add the following CPL code to the local policy file to enable this header:

define action AddXAuthHeader
set(request.x_header.X-Authenticated-User, "$(user)")
end action AddXAuthHeader

authenticated=yes action.AddXAuthHeader(yes)

For more information on how to add CPL code to the local policy file please see this KB article: How do I add CPL to a local policy file on the ProxySG?

Follow the steps below to add usernames to the X-Authenticated-User HTTP header using VPM:

  1. Login to Web Management Console of the ProxySG/ASG
  2. Navigate to Configuration -> Policy -> Visual Policy Manager and click on the "Launch" button to launch the VPM.
