Hello. Sorry for my English.

I am trying to write a plugin for authorization through several LDAP servers. And now I ran into the indicated problem, due to which the auto-creation of the user through the plugin does not work.

As I understand it, the problem is in the code "core / authentication_api.php"

if (! $ p_user_id) {
# If user id is not provided and user is not authenticated return default flags.
# Otherwise, we can get into a loop as in # 22740
if (! auth_is_user_authenticated ()) {
return new AuthFlags ();
}

if the user is absent, the function is exited without reaching the EVENT_AUTH_USER_FLAGS event.
