Samba change password on reboot request

  • I'm using a Windows 10 pro client to access a 8.0.0g mxq mediacentre with "Use Samba Password Authentication" enabled (with username & passphrase).

    Everything works well - I can access the shares, backup, configfiles etc and add files, delete files etc.

    However if I reboot the mxq mediacentre the Windows client refuses to authenticate giving a

    "The user's password must be changed before logging on for the first time"

    dialog.

    If I then go to the mxq mediacentre box and disable "Use Samba Password Authentication" and then immediately enable it again I can connect with no problem from the Windows client.

    Is this a known issue with Samba i.e. a reboot will cause a "first time login password change request" from a client?
