ничего, перекидывает обратно на форму ввода логин/пароль(без сообщения)

Значит возможны сообщения только такого типа (в спойлере).

Возможно ls виноват (может доп. прописать в ls нужно), а возможно и клиент не хочет... Можете попробывать любой другой (к примеру 1333).
Но что то мне подсказывает что используется только то что в спойлере выше... номера 1809 = 11 = 17 из спойлера (396 из SystemMsg), 1811 = 13 = 18 из спойлера(458 из SystemMsg) и 19 из спойлера (398 из SystemMsg). Вообщем как то так).
