openldap之（二）如何添加用户条目 Add Users 及如何将本地linux账户添加至ldap条目树中

openldap添加用户条目（登录后就需要设置修改密码）
声明下面的ou=Group和ou=People之前已经创建好了，参看https://wsfnk.com/archives/431.html
目录树规划

    #先生成一个密码（1234）
[root@openldap-server ~]# slappasswd
New password: 
Re-enter new password: 
{SSHA}OaR2RdktjtY2nJlPmuYPfop+QJok1OX5

    #创建新用户的ldif文件
    vi ldapuser.ldif 

#注意要顶格写.这里latiao用户，我将其加入到centos组中
# create new
# replace to your own domain name for "dc=***,dc=***" section

dn: uid=latiao,ou=People,dc=wsfnk,dc=local
objectClass: inetOrgPerson
objectClass: posixAccount
objectClass: shadowAccount
cn: centos
sn: 李
givenName: 辣条
displayName: 李辣条
userPassword: {SSHA}OaR2RdktjtY2nJlPmuYPfop+QJok1OX5
loginShell: /bin/bash
uidNumber: 2000
gidNumber: 1000
homeDirectory: /home/latiao
#shadowLastChange: 1620
#shadowMin: 0
#shadowMax: 9999
#shadowWarning: 7
#shadowExpire: 0   #若为负数，会无休无止的让你修改密码

#这是添加一个名为centos的cn，在名为Group的ou下
dn: cn=centos,ou=Group,dc=wsfnk,dc=local
objectClass: posixGroup
cn: centos
gidNumber: 1000
memberUid: centos

    #导入用户的ldif
    ldapadd -x -D cn=Manager,dc=wsfnk,dc=local -W -f ldapuser.ldif

    #验证：在客户端查看刚才添加的用户ID号
[root@centos7 ~]# getent passwd latiao
latiao:x:2000:1000:centos:/home/latiao:/bin/bash

导入本地linux的账户到openldap目录树里（先写一个脚本，用于生成本地用户信息）

    vi ldapuser.sh 

# extract local users and groups who have 1000-9999 digit UID
# replace "SUFFIX=***" to your own domain name
# this is an example

#!/bin/bash

SUFFIX='dc=wsfnk,dc=local'
LDIF='ldapuser.ldif'
