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 :
![](https://images0.cnblogs.com/blog2015/688295/201503/111432186672530.png)
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"
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
#!/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"
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"

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)
