Как получить админ доступ в CUPS?

Здравствуйте, работаю под системой Mint 17.3 полсе установки драйверов epson p50 понадобилось управление CUPS через web. Разумеется открыл доступ в настройках и добавил себя в группу lp.
Проверил, есть ли я в группе cat /etc/group | grep vitali
Ответ:
lpadmin:x:108:vitali

НО! при входе в web интерфейси попытке ввести логин и пароль учетной запис, не происходит вход!
Вот сам файл настроек, подскажите, где моя ошибка?

LogLevel warn
MaxLogSize 0
SystemGroup lp
Port 631
