windows-server-2008 – 让squid通过kerberos和Windows 2008/2003/7 / XP进行身份验证

Windows 前端之家
前端之家收集整理的这篇文章主要介绍了windows-server-2008 – 让squid通过kerberos和Windows 2008/2003/7 / XP进行身份验证，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
这是我最近设置的,并且是一个非常大的痛苦.我的环境正在变得鱿鱼无法对 Windows 2008 Server进行Windows 7客户端身份验证. NTLM实际上不是一个选项,因为使用它需要在每个客户端上更改注册表.

自从Windows 2000以来,MS一直在推荐Kerberos,所以现在终于可以开始使用该程序了.

很多,非常感谢Squid邮件列表中的Markus Moeller帮助实现这一目标.

这是使用Squid 3.0设置的,也已经过Squid 3.1测试,应该与Squid 2.7一起使用.您的Windows用户必须是Active Directory中SQUID_USERS组的成员(无论如何都是这种情况).

在Windows方面,Windows XP和Windows 2007已针对Windows 2008和Windows XP针对Windows 2003进行了测试.

请注意,几乎每个步骤都需要前面的步骤.

如果您遇到问题,DNS始终是第一个看的地方.两台Windows机器都应该能够通过名称ping Linux服务器(反之亦然),您可能需要运行ipconfig / flushdns.重新启动也可能有所帮助,如果你想确定没有任何问题.

域信息

> Windows域名：dom.local
>域服务器：server.dom.local,172.17.3.11
> CentOS squid服务器：centos.dom.local,172.17.3.10

域服务器设置

>在DNS配置中创建dom.local反向区域.
>为centos.dom.local创建指向172.17.3.10的静态(‘A’)记录,当询问是否要设置反向PTR时选择是.

Windows 2008

对于Windows 2008服务器,您需要安装Hotfix 951191.

Linux安装程序

小包装

安装包

$yum install -y cyrus-sasl-gssapi cvs autoconf automake openldap openldap-devel krb5-workstation krb5-devel gcc-c++

安装msktutil.您需要在构建之前对其进行修补.

$wget http://download.systemimager.org/~finley/msktutil/msktutil_0.3.16.orig.tar.gz
$wget http://download.systemimager.org/~finley/msktutil/msktutil_0.3.16-7.diff.gz
$gunzip msktutil_0.3.16-7.diff.gz
$tar zxf msktutil_0.3.16.orig.tar.gz
$cd msktutil-0.3.16
$patch < ../msktutil_0.3.16-7.diff
$./configure && make && make install

编译最新的squid_kerb_ldap.

$cvs -z3 -d:pserver:anonymous@squidkerbauth.cvs.sourceforge.net:/cvsroot/squidkerbauth co -P squid_kerb_ldap
$cd squid_kerb_ldap
$./configure && make

DNS

使用system-config-network配置域控制器的DNS点,将主机名设置为centos.dom.local.

重启

检查反向DNS工作正常：
$dig -x 172.17.3.10

你应该在答案部分获得centos.dom.local.如果你不这样做,那就没有意义了.如果没有正确配置DNS,Kerberos身份验证将无法运行.

Kerberos的

你的krb.conf应该是这样的：

[logging]
 default = FILE:/var/log/krb5libs.log
 kdc = FILE:/var/log/krb5kdc.log
 admin_server = FILE:/var/log/kadmind.log

[libdefaults]
 default_realm = DOM.LOCAL
 dns_lookup_realm = false
 dns_lookup_kdc = false
 ticket_lifetime = 24h

# For Windows XP:
 default_tgs_enctypes = rc4-hmac des-cbc-crc des-cbc-md5
 default_tkt_enctypes = rc4-hmac des-cbc-crc des-cbc-md5
 permitted_enctypes = rc4-hmac des-cbc-crc des-cbc-md5

# For Windows 2007:
# default_tgs_enctypes = aes256-cts-hmac-sha1-96 rc4-hmac des-cbc-crc des-cbc-md5
# default_tkt_enctypes = aes256-cts-hmac-sha1-96 rc4-hmac des-cbc-crc des-cbc-md5
# permitted_enctypes = aes256-cts-hmac-sha1-96 rc4-hmac des-cbc-crc des-cbc-md5
 forwardable = yes

[realms]
 DOM.LOCAL = {
  kdc = 172.17.3.11:88
  admin_server = 172.17.3.11:7491
  default_domain = dom.local
 }

[domain_realm]
 .dom.local = DOM.LOCAL
 dom.local = DOM.LOCAL

[appdefaults]
 pam = {
   debug = false
   ticket_lifetime = 36000
   renew_lifetime = 36000
   forwardable = true
   krb4_convert = false
}

创建密钥表：

$kinit administrator
$msktutil -c -b "CN=COMPUTERS" -s HTTP/centos.dom.local -h centos.dom.local -k /etc/HTTP.keytab --computer-name centos-http --upn HTTP/centos.dom.local --server server.dom.local --verbose

对于Windows 2008,您需要将–enctypes 28添加到msktutil命令.

乌贼

安装鱿鱼：

$wget http://www.squid-cache.org/Versions/v3/3.0/squid-3.0.STABLE18.tar.gz
$tar zxvf squid-3.0.STABLE18.tar.gz 
$cd squid-3.0.STABLE18
$./configure --enable-negotiate-auth-helpers=squid_kerb_auth --enable-stacktraces --prefix=/opt/squid-3.0
$make
$make install
$cp helpers/negotiate_auth/squid_kerb_auth/squid_kerb_auth /opt/squid-3.0/sbin/
$cp ~/squid_kerb_ldap/squid_kerb_ldap /opt/squid-3.0/sbin/
$cd /opt/squid-3.0/
$mv etc/squid.conf etc/squid.conf.ORIG

在squid.conf中设置适当的参数：

auth_param negotiate program /opt/squid-3.0/sbin/squid_kerb_auth -d -s HTTP/centos.dom.local
auth_param negotiate children 10
auth_param negotiate keep_alive o

external_acl_type SQUID_KERB_LDAP ttl=3600  negative_ttl=3600  %LOGIN /opt/squid-3.0/sbin/squid_kerb_ldap -d -g SQUID_USERS
acl AUTHENTICATED proxy_auth required
acl LDAP_GROUP_CHECK external SQUID_KERB_LDAP
acl localnet src 172.17.3.0/24        # RFC1918 possible internal network

#http_access allow localnet
#http_access allow AUTHENTICATED
http_access allow LDAP_GROUP_CHECK

cache_dir ufs /var/cache/squid-3.0 100 16 256
access_log /var/log/squid-3.0/access.log squid
cache_log /var/log/squid-3.0/cache.log
cache_store_log /var/log/squid-3.0/store.log
pid_filename /var/run/squid-3.0.pid
cache_effective_user squid
cache_effective_group squid
coredump_dir /var/cache/squid-3.0

设置用户和目录：

$chown -R squid:squid /opt/squid-3.0/
$mkdir /var/cache/squid-3.0
$chown -R squid:squid /var/cache/
$mkdir /var/log/squid-3.0
$chown -R squid:squid /var/log/squid-3.0/
$chown squid:squid /etc/HTTP.keytab

创建缓存：

$/opt/squid-3.0/sbin/squid -z

初始化脚本

现在这很重要：Squid需要一些环境变量设置才能正常运行.执行此操作的最佳方法是使用init脚本.这是一个略有编辑的CentOS：

#!/bin/bash
# squid     This shell script takes care of starting and stopping
#       Squid Internet Object Cache
#
# chkconfig: - 90 25
# description: Squid - Internet Object Cache. Internet object caching is \
#   a way to store requested Internet objects (i.e.,data available \
#   via the HTTP,FTP,and gopher protocols) on a system closer to the \
#   requesting site than to the source. Web browsers can then use the \
#   local Squid cache as a proxy HTTP server,reducing access time as \
#   well as bandwidth consumption.

esac

exit $?

这些是重要的路线：

KRB5_KTNAME=/etc/HTTP.keytab
export KRB5_KTNAME

客户端机器

使用端口3128将代理设置为服务器centos.dom.local.使用完全限定的域名而不是IP地址非常重要.
