* Host Enrollment： 主机自动注册
* Host Administrators： 主机管理
* Host Group Administrators ： 主机组管理
如果不添加主机及主机组的权限，则会提示：`Joining realm failed: No permission to join this host to the IPA domain.`

# 4 添加用户

* freeipa的密码策略是新建用户第一次强制修改密码 ，可以在任意一台已注册到`freeipa`的机器上修改密码：
```
[root@ipa1 ~]# kinit autoenroll
Password for autoenroll@SYSIT.CN: 
Password expired.  You must change it now.
Enter new password: 
Enter it again: 
```
# 5 用户授权

# 6 自动注册

```
[root@client ~]# yum install ipa-client nss-pam-ldapd nscd

[root@client ~]# ipa-client-install --enable-dns-updates --mkhomedir -p autoenroll -w autoenroll -U
