I just configured my environment to do impersonation. It works. Now for the application needs, I would like to get the header:
Reading the Policy Server Design Guide, I noticed that:
The following list contains user attributes that SiteMinder generates automatically.
When I list the header variables, I am surprised that this header is not present, even if it is told that SiteMinder generates it automatically. How can I get it?
For those automatic generated headers, you have to create a response to get them. In order to get the header:
You need to create a response for user attribute, with:
variable SM_USERIMPERSONATORNAME attribute SM_USERIMPERSONATORNAME
Bind that response to the Impersonation Start User event. Then you will be able to get the value and to pass it to your backend application.
