APM Cookbook: AutoLaunch SAML Resources

Did an update cause this to stop working? I used this a while back to link directly to SAML resouces with mixed results. Back buttons on browsers would cause weird behavior (sometimes going back inside the remote application as expected, sometimes going back to the APM logon screen, sometimes to an error from APM). The project that prompted us to try the iRule fizzled out for a while, but it has just picked up steam again. Now when I try to use one of these resources directly from the links created, i end up on a "vdesk/hangup.php3" logout screen. APM logs show an authorization failure for the SAML resource. That SAML resource is assigned to my user in the APM Policy for the webtop with which it is associated. If I log on to the webtop, i can click the link there and it works like a champ. Immediately after the SAML resource auth failure in the APM logs is a "user logout request", which I assume is the reason for the hangup screen. I would call support, but they pointed out on a previous call (i was using CamElCaSe on a string that had been lower-cased... duh) that they wouldn't be able to provide support on a user created script... If it is still working for others, we may have something gone a little sideways in APM that needs other attention, but I'm not seeing odd behavior with anything else.

Thanks!
