# Can’t get

 *  Resolved [Mike Walsh](https://wordpress.org/support/users/mpwalsh8/)
 * (@mpwalsh8)
 * [9 years, 9 months ago](https://wordpress.org/support/topic/cant-get-2/)
 * Our internal LDAP server has changed so I need to use the **wpdirauth_filterquery**
   filter in order to properly validate user logins. I was using the solution in
   [this prior support thread](https://wordpress.org/support/topic/filter-query-is-it-possible/)
   however I cannot get **wpdirauth_filterquery** to fire.
 * I’ve tried modifying my functions.php (I am using TwentyThirteen as my theme)
   as well as a dedicated plugin. The only thing I’ve been able to get to work is
   to modify the plugin code itself. For obvious reasons I don’t really want to 
   do that. My preference would be to write a simple plugin so I don’t have to worry
   about a theme update modifying functions.php either.
 * This is what I added to my functions.php:
 *     ```
       function mgcAdjustDirAuthFilter($strCurrentFilter,$strFilter,$strUsername)
       {
            error_log(sprintf("%s::%s\n", basename(__FILE__), __LINE__), 3, "/var/tmp/log.txt"); 
            return "(&(objectClass=user)(objectCategory=person)($strFilter=$strUsername))";
       }
       add_filter(‘wpdirauth_filterquery’,’mgcAdjustDirAuthFilter’,1,3);
       ```
   
 * But it never runs. I added error_log() statements within the function to trace
   execution but the text never appears and the filter is unchanged from the default
   after apply_filters runs from line 393 of wpDirAuth.php:
 * `$filterQuery = apply_filters('wpdirauth_filterquery',$filterQuery,$filter,$username);`
 * Since that didn’t work I tried creating simple plugin:
 *     ```
       <?php
       /**
        * @package MGC-wpDirAuth
        * @version 1.0
        */
       /*
       Plugin Name: MGC-wpDirAuth
       Plugin URI: http://wordpress.org/extend/plugins/tbd/
       Description: This plugin defines a filter for the wpDirAuth plugin which configures the querty to work with Mentor's LDAP configuration.

       */
   
       function mgc_AdjustDirAuthFilter($strCurrentFilter,$strFilter,$strUsername)
       {
           error_log(sprintf("%s::%s\n", basename(__FILE__), __LINE__), 3, "/var/tmp/log.txt");
           return "(&(objectClass=user)(objectCategory=person)($strFilter=$strUsername))";
       }
   
       // Setup the wpdirauth_filterquery hook
       function mgc_wpDirAuth_init() {
           error_log(sprintf("%s::%s\n", basename(__FILE__), __LINE__), 3, "/var/tmp/log.txt");
           add_filter(‘wpdirauth_filterquery’,’mgc_AdjustDirAuthFilter’,1,3);
       }
   
       add_action( 'init', 'mgc_wpDirAuth_init' );
       ?>
       ```
   
 * Like the addition to functions.php, the filter never runs. The ‘init’ action 
   does fire and I see the entry in the error log file. I’ve tried various priorities
   and other hooks (e.g. plugins_loaded and a couple others) but it didn’t make 
   a difference. The site this is running only has one other plugin running which
   does nothing more than look up information from our LDAP server.
 * I assume I am missing something obvious I simply can’t see from staring at it.

 * I’m not sure. I just tried it in a single site, and a multisite and it fired 
   correctly. specifically, i added this to my functions file:
 *     ```
       add_filter('wpdirauth_filterquery',function($filterQuery,$filter,$username){
       	__log(func_get_args(),'arguments passed to us',false,array('func'=>__FUNCTION__,'line'=>__LINE__,'file'=>__FILE__));
       	return '(' . $filter . '=foobar)';
       },1,3);
       ```
   
 * and in wpDirAuth logged the return from the filter
 * In the log, it fired and produced
 *     ```
       [06-Oct-2016 17:28:42 UTC] : At line number 279 inside of function {closure} in file functions.php 
       arguments passed to us
       The variable is a array
   
       array (
         0 => '(samAccountName=myaccount)',
         1 => 'samAccountName',
         2 => 'myaccount',
       )
   
       [06-Oct-2016 17:38:14 UTC] : At line number 394 in file wpDirAuth.php 
       filterQuery after being altered by apply filters
       The variable is a string
       (samAccountName=foobar)
       ```
   
 * I then removed that and replaced it with your function and in the log I get
 *     ```
       [06-Oct-2016 17:43:38 UTC] : At line number 394 in file wpDirAuth.php 
       filterQuery after being altered by apply filters
       The variable is a string
       (&(objectClass=user)(objectCategory=person)(samAccountName=myaccount))
       ```
   
 * So it is working properly as far as I can tell. Can you give me more info on 
   your specific setup? Multisite/single? WordPress version?
