CIFS Permission denied または "cifs_mount failed w/return code = -13" エラーの診断

Solution Verified - Updated -


  • たとえば、試しに CIFS 共有を手動でマウントします。
[root@flandre-examplebox ~]# mount -t cifs -o credentials=/etc/user-file //remilia-examplebox/pachiouli /knowledge
mount error(13):Permission denied
  • mount -a を持つ /etc/fstab を使用してマウントしても失敗します。
[root@flandre-examplebox ~]# mount -a
mount error(13):Permission denied
  • マウントしようとすると、以下のメッセージが /var/log/messages に記録されます。
Aug  9 22:39:39 flandre-examplebox kernel:Status code returned 0xc000006d NT_STATUS_LOGON_FAILURE
Aug  9 22:39:39 flandre-examplebox kernel:CIFS VFS:Send error in SessSetup = -13
