I found that because the ldap_integration module (ldapauth) bypasses the Drupal authentication system to do its dirty work, httpauth wouldn't work with LDAP users.

Here's a patch that lets it work by calling ldapauth_login_validate. It's hackish and applied to httpauth rather than the source of the problem, but httpauth is much less complex and brittle.

// Allow authentication via LDAP
    if (function_exists('ldapauth_login_validate')) {
      require_once('includes/common.inc');
      require_once('includes/unicode.inc');
      require_once('modules/user/user.module');
      require_once(drupal_get_path('module', 'ldapauth') .'/ldap_integration/LDAPInterface.php');
      $form_state = array('values' => array('name' => $name, 'pass' => $pass));
      ldapauth_login_validate(NULL, $form_state);
    }

Here's an updated patch for the latest ldap_integration (6.x-1.0-beta1) module:

// Allow authentication via LDAP
drupal_load('module', 'ldapauth');
if (function_exists('ldapauth_authenticate')) {
    require_once('includes/common.inc');
    require_once('includes/unicode.inc');
    require_once('includes/form.inc');
    drupal_load('module', 'user');
    require_once(drupal_get_path('module', 'ldapauth') .'/includes/LDAPInterface.inc');
    $form_state = array('values' => array('name' => $name, 'pass' => $pass));
    ldapauth_authenticate($form_state['values']);
}

Very interesting, I'll test this week and report.

So, it's working really well indeed. No issues in two weeks of use / testing (10,000 logins) :)

I do get an error in the log, but it does not seem to be critical:

call_user_func_array() [<a href='function.call-user-func-array'>function.call-user-func-array</a>]: First argument is expected to be a valid callback, 'httpauth_callback' was given in C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\includes\menu.inc on line 348.

Going to have a look into it later.
