    When building an LDAP filter, you should use ldap_escape with LDAP_ESCAPE_FILTER flag.

    Example #1 Searching for an email address

    <?php
    // $ds is a valid link identifier for a directory server
    // $mail is an email address provided by the user in a form
    $base   = "o=My Company, c=US";
    $filter = "(mail=".ldap_escape($mail, "", LDAP_ESCAPE_FILTER).")";
    $sr = ldap_search($ds, $base, $filter, array("sn", "givenname", "mail"));
    $info = ldap_get_entries($ds, $sr);
    echo $info["count"]." entries returned\n";
    ?>
    
    You can use it like this for filtering
    <?php
    $badSearchInput = 'Domain\username';
    $escapedSearchInput = ldap_escape($badSearchInput, null, LDAP_ESCAPE_FILTER);
    ?>
