Bill,
Thanks your information.. In my policy, I did this test.
1. In my policy, I create Request: Add HTTP Header and header name = SM_USER, value = my test id
2. Route to AFM controller2.jsp.
In my arcot afm log, I saw SM_USER header but no value. I thought I did something wrong in my policy so I tried add another HTTP Header and header name = Test, value = test.
After that, I test again. This time SM_USER still return no value but I can see Test header value in the log.
I am not sure why it delete SM_USER value. I am not sure which component (Layer7, Arcot or Siteminder) delete that value.
Thanks
Mark
