[rt-users] AD integration for external auth

I'm coming back to RT after a few years.  I am trying to set up external 
auth against our AD server.

I have a working implementation for mediawiki, so I know that it's 
possible on our system.  As far as possible I've duplicated the options 
from mediawiki/php to rt/perl, but I am still missing something 
important as all login attempts get rejected with a NoUser.

The only thing that I find different (and I'm searching my memory from a 
few years ago when I set up mediawiki) there is a line where the user 
name is pre-pended with the domain for AD:

$wgLDAPSearchStrings = array( 'HPM' => "HPM\\USER-NAME" );

And I can't find anything like that in the RT config.

Does anyone have a working AD external auth they can share?

Thanks.

Here's the logfile snippet:

And here's the setup in RTSiteConfig.pm:

Plugin('RT::Authen::ExternalAuth');
Set($ExternalAuthPriority,  [ 'My_LDAP' ]);
Set($ExternalInfoPriority,  [ 'My_LDAP' ]);
Set($ExternalSettings, {
      'My_LDAP'       =>  {
      'type'             =>  'ldap',
      'server'           =>  'file_print.hpm.net',

                 # Import the following properties of the user from LDAP

                 # login
                 'attr_map' => {
                     'Name'         => 'sAMAccountName',
                     'EmailAddress' => 'mail',

         } );
