OpenLDAP配置信息记录

liangjichen 2015-03-11 14:57 原文

随着各种研发工具使用越来越多，单独为每个工具维护一个账号系统的开销越来越大，而且作为用户多个账号密码使用也越来越不方便。所以需要做一个统一账号登陆。

查询了多个方法，又因为之前用过LDAP，所以选择了OpenLDAP来尝试实现。

OpenLDAP安装系统信息：

Ubuntu 14.04.1 LTS/CentOS release 6.5

openldap-2.4.39

关于如何安装请参考其他资料，这里仅记录一些尝试成功的配置。

OpenLDAP Commands 例子 :
ldapsearch -xLLL -b "uid=liangji.chen,ou=People,dc=example,dc=com"

ldapadd -x -D "cn=Manager,dc=example,dc=com" -w secret -f initial.ldif

ldappasswd -x -S -D "cn=Manager,dc=example,dc=com" -w secret "uid=liangji.chen,ou=People,dc=example,dc=com"
ldapsearch -h 10.0.3.140 -p 389 -x -b "uid=liangji.chen,ou=People,dc=example,dc=com" -D "cn=Manager,dc=example,dc=com" -w secret

ldapdelete -x -D "cn=Manager,dc=example,dc=com" -w secret "uid=liangji.chen,ou=People,dc=example,dc=com"

Jenkins Configuration 例子 :
Apache + SVN configuration 例子 :
<Location /svn>
  DAV svn
  SVNParentPath /var/lib/svn

 

  AuthType Basic

 

  AuthName "Subversion Repository"
  AuthBasicProvider ldap file
  AuthLDAPBindDN "cn=Manager,dc=example,dc=com"
  AuthLDAPBindPassword secret
  AuthLDAPURL "ldap://10.0.3.140:389/ou=People,dc=example,dc=com?uid"
</Location>
 
以下脚本会用到MigrationTools，这是下载地址 ： http://www.padl.com/OSS/MigrationTools.html
添加LDAP用户的脚本 [root@linux openldap]# cat adduser.sh
#!/bin/sh
#首先创建一个linux帐户
if [ -z $1 ]; then echo "Please specify username ..."; exit; fi

useradd $1
passwd $1

export PERL5LIB=./migration/
#转gid到ldap帐户
cat /etc/group | grep $1 >/tmp/group.in
migration/migrate_group.pl /tmp/group.in > /tmp/group.ldif
ldapadd -x -D "cn=root,dc=melot,dc=cn" -w secret -f /tmp/group.ldif
#转uid到ldap帐户
cat /etc/passwd | grep $1 > /tmp/passwd.in
migration/migrate_passwd.pl /tmp/passwd.in > /tmp/passwd.ldif
ldapadd -x -D "cn=root,dc=melot,dc=cn" -w secret -f /tmp/passwd.ldif
#删掉创建的linux帐户, 使帐户成为纯粹的ldap帐户，而不是local帐户
userdel $1
#rm -rf /home/$1
#rm /tmp/group.ldif
#rm /tmp/passwd.ldif
ldapsearch -x "uid=$1"   #可用于显示刚刚添加到ldap数据库中的用户信息
 
重置LDAP用户密码的脚本 [root@linux openldap]# cat resetpass.sh
if [ -z $1 ]; then echo "Please specify username ..."; exit; fi

ldappasswd -x -S -D "cn=root,dc=melot,dc=cn" -w secret "uid=$1,ou=People,dc=melot,dc=cn"
 
提供给用户自助修改密码的网页 [root@linux htdocs]# cat ldap.php

设置密码后不生效的情况，可以参考这里解决：http://www.linuxfly.org/post/671/

报错是：ldap_bind: Invalid credentials (49)
