#ldap client端的安装和配置
说明：ldap client实际上就是工作中通过ldap服务器验证登录的其他业务服务器，只是相对于ldap server才称之为客户端服务器。
#通过图形方式配置ldap client
图形方式的优点：
操作简单，少量服务器效果好，但是上千台批量操作又太麻烦了。
#验证：
[root@node2 ~]# id ldapuser1
uid=501(ldapuser1) gid=501(ldapuser1) groups=501(ldapuser1)
注：ldapuser1为ldap服务器创建的用户，客户端没有
#设定终端语言，防止乱码
export LC_ALL=en_US.UTF-8
#打包客户端配置文件

测试成功！
02、通过puppet等分发工具配置客户端家目录及变量
通过puppet等分发工具创建对应ldap用户的家目录及设置对应的权限，配置环境变量等，这个方法是推荐的的方法。
触发或定时任务，从ldap中取出新添加的账户，然后调用puppet或sshkey分发工具分发家目录或远程创建家目录，并设置环境变量。
#限制ldap用户连接
1）根据UID范围。2）根据授权文件控制
备份系统认证文件
cp /etc/pam.d/system-auth-ac{,.old.$(date +%F)_$RANDOM}
首先备份系统认证文件，同时PAM配置文件至关重要，稍有差池，用户就有可能不能登录，所以需要开两个控制台调试以防万一。
增加的内容，如下：
[root@node1 ~]# vim /etc/pam.d/system-auth-ac
在
account sufficient pam_succeed_if.so uid < 500 quiet
前添加
account required pam_checkfile.so verbose verbose muid2000 /etc/authfile.conf
其中，pam_checkfile.so为授权认证模块，这里没有该文件，所以本测试无法成功。/etc/authfile.conf是授权认证文件，需要明确列出本机可以访问的用户，这样用户访问才能登录到有权限的机器。就通过这个方法来控制ldap用户登录业务服务器权限的。
[root@node1 ~]# cd /lib64/security/
[root@node1 security]# vim pam_checkfile.so
[root@node1 ~]# echo ldapuser1 > /etc/authfile.conf
#配置ldap用户通过sudo管理ldap客户端
这个是思路的问题，实际上还是配置好sudo文件，然后根据puppet等分发工具分发sudo配置到对应的业务服务器上。
192.168.1.141 /etc/authfile.conf /etc/sudoers
#生产场景ldap客户服务器的解决方法
可以开发一个php+mysql简单的mis，资产及IP资源的管理系统，添加权限时，有管理员根据对应的服务器（一般按IP地址来）增加对应的权限，然后，通过数据库保存，并写入到authfile.conf授权文件及sudoer提升权限文件里。这些文件可以放在固定的系统目录或者通过svn来管理，最后puppet等分发工具通过从数据库、系统目录、svn库取得需要更新的权限同步到线上应用服务器，从而实现ldap客户端业务服务器的精确管理。
#LDAP slave主从复制
LDAP服务器可以备份冗余来提高系统的安全性。复制是通过slurpd提供的，它会周期性的唤醒，并检查主服务器上的日志文件，从而确定是否有任何更新。这些更新然后会传送到从服务器上。ldap slave的配置文件也是slapd.conf 。
1、什么是slurpd
slurpd(8)是在一个slapd的帮助下提供拷贝服务的守护程序。它负责把主ldap进程slapd数据库的改变分发给各个不同的slapd ldap从属服务。slapd和slurpd通过一个将更改记入日志的简单的文本文件进行通信，相当于MySQL的二进制日志一样。
2、lapd主从同步原理
slurpd守护进程是用来将主slapd上的改变传播到一个或多个从属的slapd上。一个master-slave类型的配置示例如图所示
这种配置模式可以和前面的两种配置模式之一和起来使用，在前面的两种情况中，单独的slapd不能提供足够的可用性和可靠性。
3、安装ldap slave
安装步骤和ldap master完全一样。
4、修改配置ldap master
备份ldap内容
[root@node1 ~]# ldapsearch -LLL -w oldboy -x -H ldap://etiantian.org -D "cn=admin,dc=etiantian,dc=org" -b "dc=etiantian,dc=org" > /tmp/ldapmaster.ldif
主服务器上首先停止服务
[root@node1 ~]# service slapd stop
[root@node1 ~]# cp /etc/openldap/slapd.conf{,.before_slave}
[root@node1 ~]# ls /etc/openldap/slapd.conf*
/etc/openldap/slapd.conf
/etc/openldap/slapd.conf.before_slave
[root@node1 ~]# vim /etc/openldap/slapd.conf
末尾添加
replica host=192.168.1.143:389
binddn="cn=admin,dc=etiantian,dc=org"
bindmethod=simple
credentials=oldboy ·这里是密码
replogfile /var/lib/ldap/openldap-master-replog
[root@node1 ~]# chown -R ldap.ldap /var/lib/ldap/
5、修改配置ldap slave配置
从服务器上配置文件slapd.conf如下
[root@node3 ~]# cp /etc/openldap/slapd.conf{,.before_slave}
[root@node3 ~]# vim /etc/openldap/slapd.conf
末尾添加：
updatedn "cn=admin,dc=etiantian,dc=org"
updateref ldap://etiantian.org:389
[root@node3 ~]# /etc/init.d/slapd restart
6、强制还原数据
[root@node1 ~]# scp /tmp/ldapmaster.ldif 192.168.1.143:/root
[root@node3 ~]# ldapadd -x -H ldap://192.168.1.143 -D "cn=admin,dc=etiantian,dc=org" -w oldboy -c -f ldapmaster.ldif
7、测试
[root@node1 ~]# ldapsearch -LLL -w oldboy -x -H ldap://192.168.1.141 -D "cn=admin,dc=etiantian,dc=org" -b "dc=etiantian,dc=org" | grep uid=
dn: uid=ldapuser1,ou=People,dc=etiantian,dc=org
dn: uid=ldapuser2,ou=People,dc=etiantian,dc=org
dn: uid=ldapuser3,ou=People,dc=etiantian,dc=org
[root@node1 ~]# ldapsearch -LLL -w oldboy -x -H ldap://192.168.1.143 -D "cn=admin,dc=etiantian,dc=org" -b "dc=etiantian,dc=org" | grep uid=
dn: uid=ldapuser1,ou=People,dc=etiantian,dc=org
dn: uid=ldapuser2,ou=People,dc=etiantian,dc=org
dn: uid=ldapuser3,ou=People,dc=etiantian,dc=org
删除主ldap服务器上ldapuser1用户
[root@node1 ~]# ldapdelete -x -D "cn=admin,dc=etiantian,dc=org" -w 123456 "uid=ldapuser1,ou=People,dc=etiantian,dc=org"
[root@node1 ~]# ldapsearch -LLL -w 123456 -x -H ldap://192.168.1.141 -D "cn=admin,dc=etiantian,dc=org" -b "dc=etiantian,dc=org" | grep uid=
dn: uid=ldapuser2,ou=People,dc=etiantian,dc=org
dn: uid=ldapuser3,ou=People,dc=etiantian,dc=org
[root@node1 ~]# ldapsearch -LLL -w 123456 -x -H ldap://192.168.1.143 -D "cn=admin,dc=etiantian,dc=org" -b "dc=etiantian,dc=org" | grep uid=
dn: uid=ldapuser1,ou=People,dc=etiantian,dc=org
dn: uid=ldapuser2,ou=People,dc=etiantian,dc=org
dn: uid=ldapuser3,ou=People,dc=etiantian,dc=org
[root@node1 ~]# ldapdelete -x -D "cn=admin,dc=etiantian,dc=org" -w 123456 "uid=ldapuser2,ou=People,dc=etiantian,dc=org"
[root@node1 ~]# ldapdelete -x -D "cn=admin,dc=etiantian,dc=org" -w 123456 "uid=ldapuser3,ou=People,dc=etiantian,dc=org"
[root@node1 ~]# ldapadd -x -H ldap://192.168.1.141 -D "cn=admin,dc=etiantian,dc=org" -w 123456 -f /usr/share/migrationtools/user.ldif
结果：没有成功
#人工开发脚本实现ldap数据同步
（1）定时或者触发脚本实现ldap数据同步
ldapsearch -LLL -w oldboy -x -H ldap://192.168.1.141 -D "cn=admin,dc=etiantian,dc=org" -b "dc=etiantian,dc=org" >tmp.ldif
（2）清除从库的数据
法一、比较两次备份差异，把差异部分同步到从库。
法二、清除所有从库数据，把备份恢复到从库。
ldapdelete -x -D "cn=admin,dc=etiantian,dc=org" -w oldboy "uid=ldapuser1,ou=People,dc=etiantian,dc=org"
（3）同步数据到从库
ldapadd -x -H ldap://192.168.1.143 -D "cn=admin,dc=etiantian,dc=org" -w 123456 -c -f tmp.ldif
提示：人工开发脚本实现ldap数据同步仅仅是提供一个思路给大家，实际工作中不是万不得已一般不会使用。
#配置phpldapadmin
#为ldap master配置web管理接口
ldap的web管理接口有很多，有b/s结构的，也有c/s结构的。以b/s结构的ldap-account-manager-3.7.tar.gz软件为例进行讲解
1、安装lamp服务环境
[root@node1 ~]# yum -y install httpd php php-ldap php-gd
2、下载解压配置ldap客户端软件
[root@node1 ~]# tar xf ldap-account-manager-3.7.tar.gz -C /var/www/html/
[root@node1 ~]# cd /var/www/html/
[root@node1 html]# ls
ldap-account-manager-3.7
[root@node1 html]# mv ldap-account-manager-3.7/ ldap
[root@node1 html]# cd ldap/config
[root@node1 config]# cp lam.conf_sample lam.conf
[root@node1 config]# cp config.cfg_sample config.cfg
[root@node1 config]# vim lam.conf
修改
serverURL: ldap://localhost:389
为
serverURL: ldap://192.168.1.141:389
修改
admins: cn=Manager,dc=my-domain,dc=com
为
admins: cn=admin,dc=etiantian,dc=org
修改所有的
dc=yourdomain,dc=org
为
dc=etiantian,dc=org
[root@node1 config]# chown -R apache:apache /var/www/html/ldap/
[root@node1 config]# service httpd start
#配置svn+sasl通过ldap进行身份验证
1、安装配置svn服务（非apache svn）
2、启动svn服务器的SASL验证机制
SASL全称Simple Authentication and Security Layer，是一种用来扩充C/S模式验证能力的机制。
SASL是一个胶合(glue)库，通过这个库把应用层与形式多样的认证系统整合在一起。这有点类似于PAM，但是后者是认证方式，决定什么人可以访问什么服务，而SASL是认证过程，侧重于信任建立过程，这个过程可以调用PAM来建立信任关系。在这里Memcached就是上面提到的应用层，具体的认证交给SASL库，SASL会根据相应的认证机制来完成验证功能。
默认情况下，Red Hat EnterPrise Linux安装程序会自动安装Cyrus-SASL认证包。可使用下面的命令检查系统是否已经安装了Cyrus-SASL认证包或查看已经安装了何种版本。
[root@node3 conf]# rpm -qa | grep sasl
cyrus-sasl-lib-2.1.23-15.el6_6.2.x86_64
cyrus-sasl-gssapi-2.1.23-15.el6_6.2.x86_64
cyrus-sasl-devel-2.1.23-15.el6_6.2.x86_64
cyrus-sasl-md5-2.1.23-15.el6_6.2.x86_64
cyrus-sasl-2.1.23-15.el6_6.2.x86_64
cyrus-sasl-plain-2.1.23-15.el6_6.2.x86_64
#查看密码验证机制，输入：
[root@node3 conf]# saslauthd -v
saslauthd 2.1.23
authentication mechanisms: getpwent kerberos5 pam rimap shadow ldap
当前可使用的密码验证方法有gepwent、kerboros5、pam、rimpa、shadow和ldap，为简单起见，这里准备采用shadow验证方法，也就是直接用/etc/shadow文件中的用户账户及密码进行验证。因此，在配置文件/etc/sysconfig/saslauthd中，应修改当前系统所采用的密码验证机制为shadow,即：
1、设置为shadow认证
[root@node3 conf]# vim /etc/sysconfig/saslauthd
修改
MECH=pam
为
MECH=shadow
[root@node3 conf]# /etc/init.d/saslauthd start
[root@node3 conf]# useradd oldboy
[root@node3 conf]# echo oldboy:oldboy | chpasswd
[root@node3 conf]# /usr/sbin/testsaslauthd -uoldboy -poldboy
0: OK "Success."
[root@node3 conf]# /usr/sbin/testsaslauthd -uoldboy -poldboy1
0: NO "authentication failed"
#验证成功
2、设置为ldap认证
[root@node3 conf]# vim /etc/sysconfig/saslauthd
修改
MECH=shadow
为
MECH=ldap
[root@node3 conf]# /etc/init.d/saslauthd restart
[root@node3 conf]# /usr/sbin/testsaslauthd -uoldboy -poldboy
0: NO "authentication failed"
[root@node3 conf]# /usr/sbin/testsaslauthd -uldapuser2 -p123456
0: NO "authentication failed"
[root@node3 conf]# vim /etc/saslauthd.conf
ldap_servers: ldap://etiantian.org/
#ldap_uri: ldap://ldap.oldboy.etianeian.org/
#ldap_version: 3
#ldap_start_tls: 0
ldap_bind_dn: cn=admin,dc=etiantian,dc=org
ldap_bind_pw: oldboy
ldap_search_base: ou=People,dc=etiantian,dc=org
ldap_filter: uid=%U
#ldap_filter: mail=%U@etiantian.org
ldap_password_attr: userPassword
#ldap_sasl: 0
[root@node3 conf]# vim /etc/sasl2/svn.conf
pwcheck_method: saslauthd
mech_list: PLAIN LOGIN
[root@node3 conf]# /etc/init.d/saslauthd restart
[root@node3 conf]# /usr/sbin/testsaslauthd -uoldboy -poldboy
0: NO "authentication failed"
[root@node3 conf]# /usr/sbin/testsaslauthd -uldapuser2 -p123456
0: OK "Success."
#验证成功
#更改svn配置文件sasl参数
[root@node3 ~]# cd /application/svndata/sadoc/conf/
[root@node3 conf]# vim svnserve.conf
修改
#use-sasl = true
为
use-sasl = true
[root@node3 conf]# pkill svnserve
[root@node3 conf]# svnserve -d -r /application/svndata/
