While reviewing PR improving roles registration from plugins I found and issue that basically disables roles creation from plugins. The condition return false if pending_migrations || Rails.env.test? || User.find_by_login(User::ANONYMOUS_ADMIN).nil? is always false because the User can never be found if User.current is nil. The same issue seems to be in ldap sync function. I think this is a good candidate for 1.15.3 since the error was introduced by #16982
