includes not always included

the hook_init does not always run on a page load and i found that while using my webserver auth hacks after logging in it seemed that those files were not included.

as a quick hack i made this change:

function _ldapgroups_detect_groups($user) {
global $_ldapgroups_ldap;
include_once(drupal_get_path('module', 'ldapgroups') .'/ldap_integration/ldapgroups.conf.php'); <-- my changes
require_once(drupal_get_path('module', 'ldapgroups') .'/ldap_integration/LDAPInterface.php'); <-- my changes
// Nothing to do if the user is not LDAP authentified
// or there are no groups configured.

As they are require and include once i don't think it matters that those lines appear more than once.
