使用net rpc join -U administrator
Enter administrator's password:
Joined domain TEST.什么错误都没有就加入域
net ads info -U administrator
Enter administrator's password:
Domain Name: TEST

/usr/local/samba/bin/net rpc join -U administrator

上面查看都是正常的，想给你一个目录换组
chgrp -R test File
提示无效的组 ，这样就不好给共享的文件设置权限。
请问怎么把域用户同步到samba上，并能登录samba这个机器。
getent passwd
