LDAP Authentication: Notice: Undefined variable: name in _ldap_authentication_user_login_authenticate_validate()

The subject error is thrown when the LDAP module attempts to match a user based on Persistent and Unique User ID Attribute.

Changing the variable $name in file /sites/all/modules/ldap/ldap_authentication/ldap_authentication.inc on lines 452 and 454 to $authname resolves this issue:

$user_edit = array(); // array of attributes that are changing for existing users
445 if (!$account_exists && isset($auth_conf->enabledAuthenticationServers[$ldap_user['sid']])) {
446 $ldap_server = $auth_conf->enabledAuthenticationServers[$ldap_user['sid']];
447 $puid = $ldap_server->userPuidFromLdapEntry($ldap_user['attr']);
448 if ($puid) {
449 $account = $ldap_server->userUserEntityFromPuid($puid);
450 if ($account) {
451 $account_exists = TRUE;
452 $user_edit['name'] = $authname;
453 $account = user_save($account, $user_edit, 'ldap_user');
454 user_set_authmaps($account, array("authname_ldap_user" => $authname));
455 }
456 }
457 }
