以前都很顺利，突然报错，看似是认证没通过，也配置也用户密码，还是不行，折腾好久，记录一下：
配置过程：
安装
sudo apt-get install samba
sudo apt-get install cifs-utils
改配置
sudo vim
/etc/samba/smb.conf 最后添加：
[share]
path = /home/username/Desktop/share #共享目录，提前建立好，chmod 777等
valid users = test
writable = yes
browseable = yes
sudo touch /etc/samba/smbpasswd
sudo smbpasswd -a test重启samba
sudo service smbd restart
win10下访问：
\192.168.192.129share
提示错误：
You can't access this shared folder because your organization's security policies block unauthenticated guest access.
These policies help protect your PC from unsafe or malicious devices on the network.
原因：
因为Window10 更新安全策略，默认禁止访问无密码的Samba共享
解决：
在Samba中增加用户名密码配置, 并在配置文件smb.conf 中注释掉 map to guest = bad user
如：
# This option controls how unsuccessful authentication attempts are mapped
# to anonymous connections
#map to guest = bad user
配置多个共享目录：在后面挨个加，如下：注意名称
[share]
path = /home/test/Desktop/share
valid users = test
writable = yes
browseable = yes
[Public]
path = /home/test/Public
valid users = test
writable = yes
browseable = yes
win10下访问：
\192.168.192.129Public
