# Filter query – is it possible?

 * Currently I’m entering a value into Account Filter of “aoLdapKey” as our LDAP
   server doesn’t use the default of samAccountName.
 * However I currently have to amend the PHP code for the following as there are
   two types of user in LDAP with different prefixes:
 * $filterQuery = “($filter=$username)”;
 * to
 * filterQuery = “(|($filter=AA{$username})($filter=XX{$username}))”;
 * This works ok but I’d love a way of doing this without amending the PHP every
   time a new version is pushed out.
 * Is it possible at all?
 * Thanks!
    Steve.

 * v1.7.14 added filter `wpdirauth_filterquery`.
    v1.7.15 amended filter to pass
   THREE parameters, instead of two.
 * Will pass callback function three parameters: current AD filter and the username
   of the person attempting to authenticate. callback function will need to return
   a valid AD filter that can be used for looking up the user.
 *     ```
       add_filter('wpdirauth_filterquery','mycustomcallback',10,3);
   
       function mycustomcallback($strCurrentFilter,$strFilter,$strUsername)
       {
           return "(|($strFilter=AA{$strUsername})($strFilter=XX{$strUsername}))";
       }
       ```

 * Thanks for the info – I’m just on a training course at the minute so will see
   if I can get it to work over the weekend. Need to figure out how to use add_filter
   first though – never done that before – lol!
 * Good news it can be done though 🙂
 * Cheers,
    Steve.

 * just drop the example i posted above into the functions.php file of your theme,
   changing `mycustomcallback` to the function name you want to use. Something like:
 *     ```
       add_filter('wpdirauth_filterquery','steveCliffAdjustWpDirAuthFilter',10,3);
   
       function steveCliffAdjustWpDirAuthFilter($strCurrentFilter,$strFilter,$strUsername)
       {
           return "(|($strFilter=AA{$strUsername})($strFilter=XX{$strUsername}))";
       }
       ```
