Subsequent Form Based SSO

After performing a successful APM Form Based SSO it can happen that the backend website will expire the user session while the APM session is still active. When this happens, the user will see the logon page of the backend website and needs to login again. This code snippet will try to detect that the user is being redirected to the backend website login page and will perform a Form Based SSO again by using the credentials from the active APM session.

When using this code snippet, make sure you set the below shown variables to match your environment.

set static::start_uri
set static::form_action

You should also use the Variable Assign agent in the VPE to set the APM session variable session.custom.form_based.password with the users password. This password will be used to perform the subsequent Form Based SSO. Use the following custom expression: return [mcget -secure {session.logon.last.password}].
