Centos7+OPENLDAP+SAMBA配置
本文旨在测试客户端访问samba服务器时，通过ldap进行用户的认证。用户访问samba权限则通过samba本身控制。
环境
Ldap服务器：centos7 系统 IP : 192.168.0.8 主机名：ldapnode
Samba服务器：centos7 系统 IP: 192.168.0.63 主机名：node3
服务器均关闭防火墙以及selinux
安装LDAP
配置epel源
[root@ldapnode ~]# cat /etc/yum.repos.d/epel.repo
[epel]
name=aliyun epel
baseurl=http://mirrors.aliyun.com/epel/7Server/x86_64/
gpgcheck=0
[root@ldapnode ~]#
安装ldap samba
[root@ldapnode ~]# yum install -y openldap-servers openldap-clients migrationtools samba-common samba samba-client
确保安装无误。
[root@ldapnode ~]# rpm -qa|grep ldap
compat-openldap-2.3.43-5.el7.x86_64
openldap-clients-2.4.40-13.el7.x86_64
openldap-2.4.40-13.el7.x86_64
openldap-servers-2.4.40-13.el7.x86_64
[root@ldapnode ~]# rpm -qa|grep samba
samba-common-libs-4.4.4-12.el7_3.x86_64
samba-common-tools-4.4.4-12.el7_3.x86_64
samba-client-4.4.4-12.el7_3.x86_64
samba-common-4.4.4-12.el7_3.noarch
samba-client-libs-4.4.4-12.el7_3.x86_64
samba-libs-4.4.4-12.el7_3.x86_64
samba-4.4.4-12.el7_3.x86_64
[root@ldapnode ~]#
配置时间同步
[root@ldapnode ~]# ntpdate pool.ntp.org
20 Jan 11:44:37 ntpdate[16342]: step time server 173.255.215.209 offset -28801.403434 sec
配置LDAP
生成LDAP管理员密码
[root@ldapnode ~]# slappasswd
New password:
Re-enter new password:
{SSHA}OONP2dL3kkukflJIDp4gepGR2EdfD0fN
[root@ldapnode ~]#
此处我自己设置的为123456，自定义。
拷贝数据库文件
[root@ldapnode ~]# ls /var/lib/ldap/
[root@ldapnode ~]# cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG
[root@ldapnode ~]# chown ldap:ldap /var/lib/ldap/DB_CONFIG
[root@ldapnode ~]# ls /var/lib/ldap/
DB_CONFIG
[root@ldapnode ~]#
修改ldap配置
因centos7操作系统较centos6在ldap的配置上变化很大，而我不熟悉centos7的配置。故先拷贝centos6的配置文件，进行相关samba方面的配置修改。然后通过slaptest命令进行格式转换。
下面为配置文件存放在/root下

创建用户和组并生成相关配置文件
创建4个用户分别为user1-4 创建2个组分别为test1,test2。将user1,user2加入到组test1，将user3,user4加入到组test2.
[root@ldapnode ~]# groupadd test1
[root@ldapnode ~]# groupadd test2

编辑migrationtools配置文件
[root@ldapnode ~]# vi /usr/share/migrationtools/migrate_common.ph
第71行修改domain信息
70 # Default DNS domain
71 $DEFAULT_MAIL_DOMAIN = “example.com”;
72
73 # Default base
74 $DEFAULT_BASE = “dc=example,dc=com”;
将用户跟组文件导入到ldif文件中
[root@ldapnode ~]# /usr/share/migrationtools/migrate_passwd.pl passwd user.ldif
[root@ldapnode ~]# /usr/share/migrationtools/migrate_group.pl group group.ldif
将基础数据导入到LDAP中
将以上生成的base.ldif user.ldif group.ldif导入到LDAP中
修改权限并启动ldap
[root@ldapnode ldap]# chown -R ldap:ldap /var/lib/ldap/
[root@ldapnode ldap]# systemctl start slapd
