To enable OpenID Connect
Visit the OpenID Connect tab and fill the preferences page.
Tiki uses OpenID Connect with Authorization Code, after a successful login, the user is redirected to Tiki Login page, and a code is passed as query argument. Tiki will contact the OpenID auth endpoint to exchange the code for the Access Tokens.
The redirect URL should point to tiki-login.php.
