ubuntu服务器共享文档无法连接,ubuntu14.04 Samba 共享文件无法访问问题

按常规配置后，在windows访问ubuntu的共享文件，弹出

"无法访问。您可能没有权限使用网络资源，请与这台服务器的管理员联系以查明您是否有访问权限。指定的网络名不再可用。"

最后分别查看 vim /var/log/samba/log.%m和log.sabd下的日志文件发现:

[2017/05/06 21:29:27.121208, 0] ../lib/util/become_daemon.c:111(exit_daemon)

126 STATUS=daemon failed to start: Samba detected misconfigured 'server role' and exited. Check logs for details, error code 22

131 At this time the 'samba' binary should only be used for either:

132 'server role = active directory domain controller' or to access the ntvfs file server with 'server services = +smb'
