ubuntu 共享出现password level

在共享的时候出现net usershare 返回错误 255:unknown parameter encountered:"password level"这种问题，求各位大神赐教解决方法！

楼主这是要配置samba共享给windows吗，直接在shell上操作呗
修改

 /etc/samba/smb.conf

配置你要共享的目录就可以

/etc/samba/smb.conf

 [global]
        workgroup = SAMBA
        security = user

        passdb backend = tdbsam

        printing = cups
        printcap name = cups
        load printers = yes
        cups options = raw

[homes]
        comment = Home Directories
        valid users = %S, %D%w%S
        browseable = No
        read only = No
        inherit acls = Yes

[printers]
        comment = All Printers
        path = /var/tmp
        printable = Yes
        create mask = 0600
        browseable = No

[print$]
        comment = Printer Drivers
        path = /var/lib/samba/drivers
        write list = root
        create mask = 0664
        directory mask = 0775
[usr]
        path=/home/usr
        browseable = yes
        writable = yes
        valid users = usr
