Problem with LDAP enrolment when Course is hidden.

When Ldap enrolment is used and a course is hidden, and a user is a member of the group that is assigned to the hidden course, on login a user is presented with a "blank" page....or a php error if debug is right....

caused by the following code in enrol\ldap\enrol.php function setup_enrolments(&$user)

line 79:
if ($course_obj->visible==0 && $user->{$type}[$course_obj->id] == 'ldap') {

$type doesn't exist. - and $user doesn't contain anything that looks like a CourseObj->id with a setting of 'ldap' either....

replacing it with this works:

if ($course_obj->visible==0) {
but it doesn't check to see if the course is an Ldap enrolment type.....

does it need to check this?
