Release Notes:


The LDAP debug logs are inconsistent in their use of log_auth() vs log_error() and they should all be log_error() as using log_auth() will result in console alerts.

Also the messages could use a consistent prefix such as "LDAP Debug".

Would also help to log debug info in a few more cases along the code path plus a summary of settings.

And then to make it actually useful, add a 'debug' option to diag_authentication.php which will trigger this logging.

See also: #13093

To me, I already have the changes done, this is to make sure it gets listed in the release notes.

N.B.: There is still room for further improvement in future versions and also we could add similar debugging to radius auth and so on eventually.

This is working well. Go to Diag > Auth, pick the server, enter the credentials, check the debug box and:
