4. TEST Result 

kinit user

klist

net ads join -U admin(join domain)

wbinfo -t (confirm the result of joining domain)

wbinfo --group-info  XXX\\domin\ users(if error , please enable ipv6, smb.conf idmap)

wbinfo -a XXX\\testuser%‘password‘  (test the domain user and password)

5. /usr/sbin/exe_wbinfo_group_acl 

authen windows AD group members.

Squid parameter explain:

1.max_user_ip(one user with 2 IP address will be deny in bellow settings)

2.proxy_auth REQUIRED (AD uers no need password, others need username and password.)

3.authenticate_ip_ttl (squid remember the user with IP address time)

acl FOO max_user_ip 2
acl BAR proxy_auth REQUIRED
http_access deny FOO
http_access allow BAR
