* Windows 2008上需要把Linux-NSS用户加到Administrators组，这样Linux-NSS才有加AD的权限。

smb.conf配置(红色部分为authconfig-tui之后要修改或增加的内容)：

补充，上文中在加入AD域时碰到“DNS update failed!”的错误，这是因为默认Linux客户端没有和Windows AD服务器在同一个域里面。可通过在Linux客户端的/etc/hosts里面加条和Windows AD服务器在同一个域(ad.example.com)的主机名解决：
[[email protected] ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
