This snippet solves a challenge where Client Initiated Form Based SSO is required but you have no available trigger that you can configure to allow APM to detect the form.
You have to install a single irule on the Virtual Server protecting the web application. This irule use ACCESS commands so assuming you have APM and an access profile is attached to the Virtual Server.
Hi Yann, thanks for sharing this. It came to good use today. However, I had to make one small adjustment. It had to do with jQuery. I had to include the jQuery library, because the website didn't use jQuery. See below an example of the changes I made to the HTTP_RESPONSE_DATE event.
set jquery "<script src='https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js'></script></head>"
set newpayload [string map [list "</head>" $jquery] $payload]
set newpayload [string map [list "</html>" $sso] $newpayload]
Thank you for your feedback. Indeed, the script has been built for Citrix Storefront and thus JQuery was already loaded.
I will update the original content with your code.
Thanks again for your help
Hi Yann, thanks for updating. I stumbled into another error. An user was using the ampersand character in the password. The solution in this case was to use URI::encode the password. The client was already sending the Content-Type: application/x-www-form-urlencoded header, so there was no need to add this header. See the changes in the HTTP_REQUEST_DATA event below.
set password [URI::encode [ACCESS::session data get -secure session.sso.token.last.password]]
set newpayload [string map [list "f5-sso-token" $password] $payload]
