[squid-users] max_user_ip doesn't work properly

Hi all.

on Squid2.5.STABLE2 i found that there is a problem with "acl max_user_ip".
I use this feature to limit users to use Internet from one PC only in the
same time. It works fine only in case if the same authentication method is
using on both PCs, i.e. NTLM (if users on both PCs use IExplorer) or Basic
(if they use any others browsers).

My configuration (a part of "squid.conf" file):

# All users must log in
acl authenticated proxy_auth REQUIRED
http_access deny !authenticated
deny_info ERR_AUTH_FAILED authenticated

# No users may share their login/password with others
acl MaxIP max_user_ip -s 1
http_access deny MaxIP
deny_info ERR_MAX_USER_IP MaxIP

# vip_users allowed always
acl vip_users proxy_auth "/path/to/vip_users"
http_access allow vip_users

How to limit the users with "acl max_user_ip" feature not depending on
browser they use?

Thanks.
