可实现的功能：
1：OpenLDAP服务端的搭建
2：PhpLDAPAdmin的搭建(便于web页面管理)
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
6：OpenLDAP结合客户端PAM，限制用户登录主机
7：OpenLDAP加入密码策略
（1）强制用户首次登录系统更改密码
（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）是否允许用户修改密码
（9）账号锁定后，不能自动解锁，需管理员解锁
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
service iptables stop chkconfig iptables off sed -i ‘s@SELINUX=enforcing@SELINUX=disabled@g‘ /etc/selinux/config
（3）时间同步
yum -y install ntp /usr/sbin/ntpdate -u clepsydra.dec.com tick.ucla.edu ntp.nasa.gov echo "1 2 * * * /usr/sbin/ntpdate -u clepsydra.dec.com tick.ucla.edu ntp.nasa.gov" >> /var/spool/cron/root
1.2 源码安装OpenLDAP
（1）yum安装依赖包
yum -y install gcc gcc-c++ unzip gzip bzip2 openssl-devel cyrus-sasl-devel krb5-devel tcp_wrappers-devel libtool-ltdl-devel openslp-devel unixODBC-devel mysql-devel
（2）源码安装Berkeley DB
cd /usr/local/src/ wget http://download.oracle.com/berkeley-db/db-4.6.21.tar.gz tar xf db-4.6.21.tar.gz cd db-4.6.21/build_unix/ ../dist/configure --prefix=/usr/local/BDB4 make && make install echo "/usr/local/BDB4/lib" >> /etc/ld.so.conf.d/bdb.conf ldconfig ln -sv /usr/local/BDB4/include /usr/local/bdb

（2）测试同步
1.8 Keepalived+OpenLDAP实现OpenLDAP高可用
（1）下载安装keepalive
cd /usr/local/src/ wget http://www.keepalived.org/software/keepalived-1.2.13.tar.gz yum install -y pcre-devel openssl-devel popt-devel tar xf keepalived-1.2.13.tar.gz cd keepalived-1.2.13 ./configure --prefix=/usr/local/keepalived make make install
（2）配置keepalived配置成系统服务
cd /usr/local/keepalived/ cp etc/rc.d/init.d/keepalived /etc/init.d/ cp etc/sysconfig/keepalived /etc/sysconfig/ mkdir /etc/keepalived cp etc/keepalived/keepalived.conf /etc/keepalived/ cp sbin/keepalived /usr/sbin/ chkconfig keepalived on chkconfig --list keepalived

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
service iptables stop chkconfig iptables off sed -i ‘s@SELINUX=enforcing@SELINUX=disabled@g‘ /etc/selinux/config
（3）时间同步
yum -y install ntp /usr/sbin/ntpdate -u clepsydra.dec.com tick.ucla.edu ntp.nasa.gov echo "1 2 * * * /usr/sbin/ntpdate -u clepsydra.dec.com tick.ucla.edu ntp.nasa.gov" >> /var/spool/cron/root
1.2 源码安装OpenLDAP
（1）yum安装依赖包
yum -y install openldap openldap-devel compat-openldap nss-pam-ldapd
（2）备份源文件
cp /etc/nslcd.conf /etc/nslcd.conf_default cp /etc/nsswitch.conf /etc/nsswitch.conf_dafault cp /etc/pam.d/system-auth-ac /etc/pam.d/system-auth-ac_default cp /etc/pam.d/password-auth-ac /etc/pam.d/password-auth-ac_default cp /etc/pam.d/fingerprint-auth-ac /etc/pam.d/fingerprint-auth-ac_default cp /etc/pam.d/smartcard-auth-ac /etc/pam.d/smartcard-auth-ac_default cp /etc/pam.d/sshd /etc/pam.d/sshd_default cp /etc/pam.d/login /etc/pam.d/login_default cp /etc/openldap/ldap.conf /etc/openldap/ldap.conf_defalut cp /etc/sudo-ldap.conf /etc/sudo-ldap.conf_default
