为什么不能设置 security=share?附smb.conf文件内容

zj21cn

smb.conf
[global]
        add machine script = /usr/sbin/useradd  -c Machine -d /var/lib/nobody -s /bin/false %m$
        domain logons = No
        domain master = No
        security = user
        workgroup = workgroup
#       idmap gid = 10000-20000
#       idmap uid = 10000-20000

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

[printers]
        comment = All Printers
        path = /var/spool/samba
#       browseable = yes
#       public = yes
        writable = no
        printable = yes
        read only = No

[zjtest]
        inherit acls = Yes
        path = /home/zjtest
        read only = No

## Share disabled by YaST
# [netlogon]

想把一个文件夹完全共享,修改security =share,注释[global]前三条设置.但启动samba后，smb.conf恢复原样。删掉那三条设置，从win共享仍然需要密码。
