Не могу попасть в конфигуратор CUPS (http://localhost:631/admin)

Ситуация /etc/cups/cupsd.conf: 

<Location /admin>
AuthType Digest

# на самом деле не важно Group или User
AuthClass Group
AuthGroupName sys

Order Deny,Allow
Deny From All
Allow From 127.0.0.1
</Location>


# cat passwd.md5
srr:sys:e96a1488e80deec600fe22d4d3e8c324

Доступ есть, естественно без пароля. 

Как получить работающий доступ с паролем?
