If you're not using forms in OWA, you have to access those options by inserting some special headers. This is the same thing that Forefront/TMG/whatever does when it does Forms Auth --> HTTP Auth. Like you're doing with APM.

Two headers "X-Experience" and "X-LogonType" control it:

X-Experience can be "premium" or "light". X-LogonType can be "public" or "private".

To append the headers, you'd set a custom (whatever you want) session variable during Access Policy execution, then you can use something like this on the APM vs:

when ACCESS_ACL_ALLOWED {
  if { [ACCESS::session data get "session.somecustomvariableyoucansetintheaccesspolicy"] contains "somevalueyousetforlightmode" } {
    HTTP::header replace "X-Experience" "light"
  }
  else {
   HTTP::header replace "X-Experience" "premium"
  }
}

Hi Lucas, the outlined code to mimic the "X-Experience" functionality of Forefront TMGs is not complete/correct. The valid "X-Experience" header values are "Premium" or "Basic". In addition a Forefront TMG changes the User-Agent-header value to a non-MSIE browser if Light-Mode is selected. The Public/Private-Mode setting of Forefront TMGs has beside of the "X-LogonType"-Headers some additional server-side (aka. TMG) and also client-side (aka. Browser) functionality. Basically it enables two independent TMG-Login-Cookie profiles to controll the Max-Session-Lifetime/Max-Session-Timeout and also enables persistent cookies for the private mode (e.g. required for SharePoint Browser/Office SSO Scenarios). In addition the Private-Mode stores the last-entered username string into a client-side generated cookie to autofill the username for subsequent logons. Cheers, Kai
