I'm trying to setup this plugin for Active Directory. The installation seems to be OK, but when I configure the plugin
( after completing the dialog box) I get an " Unauthorized " message when I press the test button, hence, I can't continue with the configuration.

Am I missing something ?
The server is an 2008 R2 service pack 1 fully patched.
I even tried with the GroupWise service pack 1, but that doesn't bring me any further.
