Unit8 ldap网络帐号

1.ldap是什么

ldap目录服务认证，和windows活动目录类似，就是记录数据的一种方式

2.ldap客户端所须软件

yum sssd krb5-workstation -y

3.如何开启ldap用户认证

authconfig-tui

<当出现以下报错时>

┌────────────────┤ Warning ├─────────────────┐

│                                            │

│ To connect to a LDAP server with TLS       │

│ protocol enabled you need a CA certificate │

│ which signed your server‘s certificate.    │

│ Copy the certificate in the PEM format to  │

│ the ‘/etc/openldap/cacerts‘ directory.     │

│ Then press OK.                             │

│                                            │

│                  ┌────┐                    │

│                  │ Ok │                    │

│                  └────┘                    │

│                                            │

│                                            │

└────────────────────────────────────────────┘

时因为tls的证书缺失，需要到服务器端下载所需要的证书到/etc/openldap/cacerts，

用到的命令

wget http://172.25.254.254/pub/example-ca.crt

<测试>

getent passwd ldapuser1

如果用户信息可以正常显示，证明客户端认成功。

4.自动挂载用户家目录

yum install autofs -y

vim /etc/autofs.master

/home/guests/etc/auto.ldap

vim /etc/auto.ldap

ldapuser1172.25.254.254:/home/guests/ldapuser1

+++++++++++++++++++++++++++++++++++++++++++++++++++++++

*172.25.254.254:/home/guests/&

systemctl restart autofs
