I have a question: Is it possible to set up a domain controller so
that when a user changes their password it executes a script,
regardless of what the script does.

Example:

1) USER -> changes password via CTRL+ALT+DEL.
2) Password is successfully changed in domain -> script is executed
"Hello World!!"
3) END

What I'm looking for is analogous to a database trigger on update.
Language of a solution is not a problem. I just need to know if it is
indeed possible and if so where do I look to find examples/
documentation?

Thank you for any help or direction provided.
