samba的map to guest=Bad user无用

aleng

guest account = guest
map to guest = Bad User
map to guest = Bad Password
本人在linux中新建了guest用户
名guest
密码123
本人在smbpasswd中新建了guest
smbpasswd -a guest

密码456

客户端xp用guest-456正常访问某个共享，能弹出用户名密码输入框

但是 加上 map to guest = Bad User和 map to guest = Bad Password
重起服务后客户端直接出错，不能弹出用户名密码输入框
