DYPA IdP Simulator (development only)
This is your DYPA stand-in — no real IdP needed. It authenticates
server-to-server and logs you in. The AFM must belong to a Moodle user whose
ID number (idnumber) equals it. Delete this file when done.
Optional: to also test the login-page button, set the plugin's
DYPA authentication URL to this file's URL, then click “Log in with DYPA”
on the Moodle login page — it will land you here.
