ubuntu – Samba：会话设置失败：NT_STATUS_LOGON_FAILURE

$smbclient -L localhost
Enter stivlo's password:
session setup Failed: NT_STATUS_logoN_FAILURE

这是我的/etc/samba/smb.conf

[global]
   workgroup = obliquid
   server string = %h server (Samba,Ubuntu)
   dns proxy = no
   log file = /var/log/samba/log.%m
   max log size = 1000
   syslog = 0
   panic action = /usr/share/samba/panic-action %d
   security = user
   encrypt passwords = true
   passdb backend = tdbsam
   obey pam restrictions = yes
   unix password sync = yes
   passwd program = /usr/bin/passwd %u
   passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
   pam password change = yes
   map to guest = bad user

[www]
    path = /var/www
    browsable = yes
    read only = no
    create mask = 0755

修改后我重新启动了服务器：

$sudo restart smbd
$sudo restart nmbd

但是我仍然无法使用我的Unix用户名和密码登录.

有人可以帮忙吗？先感谢您！
