OpenID Connect Generic Client

Most OAuth2 servers will require whitelisting a set of redirect URIs for security purposes. The Redirect URI provided by this client is like so: https://example.com/wp-admin/admin-ajax.php?action=openid-connect-authorize Replace example.com with your domain name and path to WordPress.

Some OAuth2 servers do not allow for a client redirect URI to contain a query string. The default URI provided by this module leverages WordPress's admin-ajax.php endpoint as an easy way to provide a route that does not include HTML, but this will naturally involve a query string. Fortunately, this plugin provides a setting that will make use of an alternate redirect URI that does not include a query string. On the settings page for this plugin (Dashboard > Settings > OpenID Connect Generic) there is a checkbox for Alternate Redirect URI. When checked, the plugin will use the Redirect URI https://example.com/openid-connect-authorize.
