Samba 4.5 中丢失写入权限

我将一台机器从 Debian Jessie 更新到 Stretch，同时将 Samba 版本从 4.2.14 升级到 4.5.16。我可以挂载 Samba 共享，浏览和读取它，但是当我尝试写入某些内容时，权限被拒绝。

我的 smb.conf 看起来像这样并且在 Samba 4.2.14 上运行良好：

[global]
   workgroup = video
   server string = %h server (Samba %v)
   dns proxy = no
   log file = /var/log/samba/log.%m
   max log size = 1000
   panic action = /usr/share/samba/panic-action %d
   obey pam restrictions = yes
   invalid users = root
   security = user  
   map to guest = Bad User
   os level = 33
   socket options = TCP_NODELAY
   unix charset = UTF-8
   strict allocate = yes
   log level = 3

[backup]
   comment = backup
   path = /mnt/backup
   writeable = yes
   public = yes
   force user = vdr
   read only = no
   guest ok = yes

我在 Samba 日志中发现以下内容：

[2020/07/15 09:55:06.621634,  3] ../source3/auth/auth.c:178(auth_check_ntlm_password)
  check_ntlm_password:  Checking password for unmapped user []\[vdr]@[] with the new password interface

  No such user vdr [] - using guest account

用户 vdr 存在于 /etc/samba/smbpasswd 中。我还应该在哪里查找？

答案1

回答我自己的问题：smbpasswd -a vdr解决了我的问题。看来 Samba 4.5 比 Samba 4.2 更加严格了。
