本文介绍如何在CentOS环境下使用Username/Password方式配置Open***服务器，并与MySQL数据库结合进行用户验证。此外，还提供了客户端配置指南。
本文档要介绍使用Username/Password方式验证登录×××的方法，虽然使用的是User/Pass方式登录，但是在Server端仍然需要证书，这样的×××和web的HTTPs方式有点类似(不能等同)，只需Server端有证书，Client可以不提供自己的证书，Client只需验证Server的合法性即可，所以Client端只需ca.crt(根证书)即可。当然，由于Client不是使用证书验证的，所以安全性方面必然有所下降，但是省去了烦琐的CA管理，我们可以通过用户名和密码来登录×××，这样使得×××可以很容易和论坛、邮件系统或者其他统一验证系统结合，使用现成的管理界面。
下面开始介绍×××的安装和配置：
环境：
OS: Centos (在公司网络出口处，作路由或者是NAT设备使用)
eth0: *.*.154.166 (外网地址，直接与Internet相连)
eth1: *.*.1.166 (内网地址)
Client端硬件及网络环境配置：
OS: Windows7，IP地址不固定
Server端配置
首先检查pam-devel包是否安装，可以yum安装该软件包

What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.

crypt(0)-- Used to decide to use MySQL's PASSWORD() function or crypt()
0= No encryption. Passwords in database in plaintext. NOT recommended!
1= Use crypt
2= Use MySQL PASSWORD() function
#crypt=0:明文密码
#crypt=1: 使用crpyt()函数(对应SQL数据里的encrypt()，encrypt()随机产生salt)
#crypt=2: 使用MYSQL中的password()函数加密。
#根据mysql内创建用户时配合使用 ipad用户使用password函数加密 所以用crypt=2
