[squid-users] Acl.cc(26) AuthenticateAcl: authentication not applicable on intercepted requests.

*Hi,I'm use centos 6.5 x86_64, squid:3.1.10 AD WINDOWS SERVER 2008*

acl localnet proxy_auth REQUIRED src 172.18.1.0/24

#
# Recommended minimum Access Permission configuration:
#
# Only allow cachemgr access from localhost
http_access allow ad_net
http_access allow manager localhost
http_access deny manager
http_access deny all

# Deny requests to certain unsafe ports
http_access deny !Safe_ports

# Deny CONNECT to other than secure SSL ports
http_access deny CONNECT !SSL_ports

# We strongly recommend the following be uncommented to protect innocent
# web applications running on the proxy server who think the only
# one who can access services on "localhost" is a local user
#http_access deny to_localhost
visible_hostname iptables
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#

# Example rule allowing access from your local networks.
# Adapt localnet in the ACL section to list your (internal) IP networks
# from where browsing should be allowed
http_access allow localnet
http_access allow localhost

# And finally deny all other access to this proxy
http_access deny all

# Squid normally listens to port 3128
http_port 3128 transparent

# We recommend you to use at least the following line.
hierarchy_stoplist cgi-bin ?

# Uncomment and adjust the following to add a disk cache directory.
#cache_dir ufs /var/spool/squid 100 16 256

# Leave coredumps in the first cache dir
coredump_dir /var/spool/squid

# Add any of your own refresh_pattern entries above these.
refresh_pattern ^ftp: 1440 20% 10080
refresh_pattern ^gopher: 1440 0% 1440
refresh_pattern -i (/cgi-bin/|\?) 0 0% 0
refresh_pattern . 0 20% 4320

*Then I'm create a group "net",username "a" in the group.
As the squid.conf,:
acl localnet proxy_auth REQUIRED src 172.18.1.0/24
acl ad_net external ldap_users net
http_access allow ad_net.
But it didn't take effect.
I use user "a" logon in the domain client PC.
But it doesn't auth for squid.
