搭建一套OpenLDAP系统，实现账号的统一管理
可实现的功能：
1：OpenLDAP服务端的搭建
3: OpenLDAP服务端配置分组管理用户sudo权限分配；
（1）默认没有sudo权限；
（2）运维具有sudo到任何用户执行任何命令权限；
（3）研发具有相应的配置执行命令权限
4：OpenLDAP客户端的配置
5：OpenLDAP与SSH
7：OpenLDAP加入密码策略
（2）密码最小设置长度
（3）密码设置强度
（4）密码过期前警告天数
（5）密码过期后不能登录的天数
（6）密码尝试次数，被锁定
（7）密码失败后恢复时间
8：MirrorMode同步实现OpenLDAP双主模式
9，Keepalived+OpenLDAP实现OpenLDAP高可用
10，TCP Warppers
账号集中管理系统访问和维护流程：

一，安装OpenLDAP服务端
（俩台主安装方法一样）
1.1 基础环境配置
（1）系统初始化（参见http://wupengfei.blog.51cto.com/7174803/1955545）
（2）关闭防火墙与SElinux
serviceiptablesstop chkconfigiptablesoff sed-i's@SELINUX=enforcing@SELINUX=disabled@g'/etc/selinux/config
（3）时间同步
yum-yinstallntp /usr/sbin/ntpdate-uclepsydra.dec.comtick.ucla.eduntp.nasa.gov echo"12***/usr/sbin/ntpdate-uclepsydra.dec.comtick.ucla.eduntp.nasa.gov">>/var/spool/cron/root
1.2 源码安装OpenLDAP

二，安装OpenLDAP客户端
2.1 基础环境配置
（1）系统初始化（参见http://wupengfei.blog.51cto.com/7174803/1955545）
（2）关闭防火墙与SElinux
serviceiptablesstop chkconfigiptablesoff sed-i's@SELINUX=enforcing@SELINUX=disabled@g'/etc/selinux/config
（3）时间同步

1.2 源码安装OpenLDAP
（1）yum安装依赖包
yum-yinstallopenldapopenldap-develcompat-openldapnss-pam-ldapd
（2）备份源文件
