一:测试目标:

LDAP简介: LDAP(Lightweight Directory Access Protocol, 是轻量目录访问协议)是跨平台的和标准的协议,使用389号端口。因此应用程序就不用为LDAP目录放在什么样的服务器上操心了。实际上,LDAP得到了业界的广泛认可,因为它是Internet的标准。厂商都很愿意在产品中加入对LDAP的支持,因为他们根本不用考虑另一端(客户端或服务端)是怎么样的。
     某企业内部使用Windows的域环境进行统一管理,随着企业移动设备的增多,企业内部需要使用无线网络来满足日益增加的移动性设备的连网需求,要求用户连接无线网络时,使用Windows AD database做认证。并且不同的group有不同的接入权限。
所有无线用户使用web portal方式进行认证,认证的用户帐号使windows AD中的数据库,并且根据AD中用户所处的group属性值进行授权。(不同的group做不同的权限处理)
例如:arubatest组:为企业内网员工,可以访问所有
Arubaguest:为企业访客,只能访问公网,不能访问企业内网。
二:测试拓扑:
 

三:测试设备:
1:IMB T400笔记本2台,一台安装AD(windows 2003),另一台做测试客户端(windows 7);
2:1Aruba 650 controller做NAS;
3:1AP 125。
四:测试过程:
1:AD Server的安装与配置;
2:controller的配置;
3:客户端结果测试。
五:测试总结
--------------------------------------------------------------------------------

:测试过程:
 
1:AD Server的安装与配置:
 
(1):配置Windows AD 2003 Server ,安装AD。 (域名为test.my3377.com)
 
(2):AD上添加一个管理用户(也可以是用户原有的管理用户,测试为测试添加的管理帐户),添加用户holtzhang,密码123.com,将这个用户隶属于域管理用户
 

 
(3):AD上Users新建一个用户组,arubatest和arubaguest。
 
(4):AD上Users新建一个用户holtzhangtest,将此用户隶属于arubatest组,
新建一个用户holtzhangguest,将此用户隶属于arubaguest组。
属于arubatest组的用户可以访问所有
属于arubaguest组的用户不能访问内网,例如: 10.1.49.254,允许访问公网。
     密码统一为123.com
 
(5):记住AD的域名(test.my3377.com),在AD端的配置基本完成。

2: Aruba controller的配置

(Aruba650) #show aaa authentication-server ldap test-ldap-server
 
LDAP Server "test-ldap-server"
------------------------------
Parameter                                Value
---------                                -----
Host                                     192.168.10.111
Admin-DN                                 cn=holtzhang,cn=Users, dc=test,dc=my3377,dc=com
Admin-Passwd                             ********

端口为默认389

普通名称标示符为sAMAccountName,不用管。

所谓“著名名称”即查询的起点 base_DN,可以在这指定搜索路径,也可以只指定根。

格式为DC=abc,DC=com,按照实际域名为准

注:Aruba controller对中文支持不好,不能识别带有中文字的base_DN

 
通过aaa test-server测试在AD上添加的用户holtzhangtest能够通过认证测试。

可以观察上述返回属性,通过选取在AD上各个组不同的属性来给controller进行role的匹配。在本次测试中选用了红色字体的部分,即使用返回不同的组属性做为条件让controller进行权限的分配。
 
 //在AC上通过用户返回的组数属性进行授权
(Aruba650) (config) #aaa server-group captive-portal-server-group
(Aruba650)(ServerGroup"captive-portal-server-group")#
set role condition memberof equals CN=arubatest,CN=Users,DC=test,DC=my3377,DC=com set-value arubatest
 
(Aruba650) (Server Group "captive-portal-server-group") #

(Aruba650) (Server Group "captive-portal-server-group") #exit
 
(Aruba650) #show aaa server-group captive-portal-server-group

3         memberof   equals     CN=arubatest,CN=Users,DC=test,DC=my3377,DC=com   String set role arubatest   No
 

3:客户端测试过程
下面对用户进行测试
测试holtzhangtest帐户:
 

(Aruba650) #show user
192.168.20.253 00:22:fa:b4:9d:dc holtzhangtest arubatest 00:00:09    Web             00:1a:1e:c1:24:8e Wireless holtzhang-LDAP/00:1a:1e:92:48:f0/a-HT ht-captive-aaa-profile tunnel        Win XP
 
User Entries: 1/1
 
 

 

发现holtzhangtest用户可以访问公网,也可以访问内网。(也就是说可以访问所有。)
 

测试holtzhangguest帐户:
 

(Aruba650) #show user
192.168.20.253 00:22:fa:b4:9d:dc holtzhangguest  arubaguest 00:00:00    Web             00:1a:1e:c1:24:8e Wireless holtzhang-LDAP/00:1a:1e:92:48:f0/a-HT ht-captive-aaa-profile tunnel        Win XP
 

 

 
 
 
发现holtzhangguest用户可以访问公网,但不可以访问内网。(跟我们在AC上配置的role权限完全匹配。) 

五:测试总结
 
                                   测试时间:2012.2.23号

其它无线厂家
Aruba
其它无线厂家controller可以做到基于LDAP认证,但不能通过LDAP返回的用户属性值进行权限的分配。
其它无线厂家可以做到基于LDAP认证,可以通过LDAP返回的用户属性值进行权限的分配。
 
但此处注意,不支持中文OU,不支持中文group,不支持中文user。
 

目前各大厂家controller基本都支持LDAP认证,但不能基于LADP做授权,Aruba目前可以基于LADP做认证和授权,但只支持英文认证和授权.
