squid 3 配置LDAP及简单用户认证

废话不多说，直接上配置档。

root@redhat7 squid]# vim /etc/squid/squid.conf

#
# Recommended minimum configuration:
#
# Example rule allowing access from your local networks.
# Adapt to list your (internal) IP networks from where browsing
# should be allowed
visible_hostname redhat7     #增加此字段的原因是日志一直报错，没有hostname.
acl localnet src 10.0.0.0/8     # RFC1918 possible internal network
acl localnet src 172.16.0.0/12  # RFC1918 possible internal network
acl localnet src 192.168.0.0/16 # RFC1918 possible internal network
acl localnet src fc00::/7       # RFC 4193 local private network range
acl localnet src fe80::/10      # RFC 4291 link-local (directly plugged) machines


acl SSL_ports port 443
acl Safe_ports port 80          # http
acl Safe_ports port 21          # ftp
acl Safe_ports port 443         # https
acl Safe_ports port 70          # gopher
acl Safe_ports port 210         # wais
acl Safe_ports port 1025-65535  # unregistered ports
acl Safe_ports port 280         # http-mgmt
acl Safe_ports port 488         # gss-http
acl Safe_ports port 591         # filemaker
acl Safe_ports port 777         # multiling http
acl CONNECT method CONNECT
#auth_param basic program /usr/lib64/squid/basic_ncsa_auth /etc/squid/passwdp. 这个是使用简单的用户名密码验证。

auth_param basic program /usr/lib64/squid/basic_ldap_auth -R -b "dc=domain,dc=com" -D "cn=LDAPuser,ou=test,ou=test-ou,dc=domain,dc=com" -w "password123321" -f sAMAccountName=%s -h 192.168.1.1     #此句是使用LDAP认证，搞了好久才找对格式。

acl auth_user proxy_auth REQUIRED
#
# Recommended minimum Access Permission configuration:
#
# 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


# Only allow cachemgr access from localhost
http_access allow localhost manager
http_access deny manager


# 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


#
# 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  禁止本地网段
http_access allow localhost

# And finally deny all other access to this proxy

#允许认证的用户，与上文使用acl auth_user proxy_auth REQUIRED相呼应

http_access allow auth_user 


# Squid normally listens to port 3128
http_port 3128


# 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
