LDAP filters are not used

[cuylerj]

While the LDAP configuration page allows one to set a "User Object Filter - [The filter to use when searching user objects. Example: (&(objectCategory=Person)(sAMAccountName=*))]", and this is written to includes/config/tp.config.php as ldap_user_object_filter, that setting is not used anywhere, The only place ldap_user_object_filter appears is in pages/ldap.php, includes/config/tp.config.php and the various translation pages under includes/language/. It does not appear to be used by the rest of the code.
