Reset forgotten user password iRule = Sideband

My plan:

1. Build a lightweight IIS web site on my Web Server
2. Add code (C sharp) to reset password and Set the 'Change Password at next logon' based on a string (username) received in the query example :
3. Create an irule to perform a sideband connection => send the username and get a success result
4. go on with the APM policy if result is OK.
5. User will get a random password and will be asked to change it by APM on next logon

What do you guys think?
