建立的两个用户名为：fred wssxr.每个用户都在系统里和SMB里设置了相同的密码。
[root@localhost ~]# useradd wssxr
[root@localhost ~]# useradd fred
[root@localhost ~]# passwd wssxr
Changing password for user wssxr.
New UNIX password:
BAD PASSWORD: it is too simplistic/systematic
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
[root@localhost ~]# passwd fred
Changing password for user fred.
New UNIX password:
BAD PASSWORD: it is too simplistic/systematic
Retype new UNIX password:

[root@localhost ~]# smbpasswd -a wssxr

两个用户在客户2000server和XP上都可通过验证打开TMP目录并且可建立删除文件。但就是打不开宿主目录和个人共享目录。
谁告诉我错在这里了？
谢谢大家先。。。。。。。。
