need help with debugging

Hi @scottjl there are a few places you can check on this.

First, make sure that the correct information is entered in the Authorizer plugin settings under the External Service tab.

Also, please make sure that your AD server is configured to allow requests from the webserver that the WordPress instance is installed on.

Additionally, you can add some logging statements in the plugin around https://github.com/uhm-coe/authorizer/blob/master/src/authorizer/class-authentication.php#L168 or https://github.com/uhm-coe/authorizer/blob/master/src/authorizer/class-authentication.php#L501 to get logging information.

Please see https://www.php.net/manual/en/function.error-log.php for more information on logging errors in PHP.
