I'm using Samba Version-4.1.6-Ubuntu. I can connect to it fine from Mac OS 10.x and Win 8 & 8.1. As soon as installed the Win 10 technical preview i get the message The account is not authorized to log in from this station.

I have done/tried the following:

- Rebooted the client
- Rebooted the server
- Upgraded all the packages on the server
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanworkstation\parameters\enablesecuritysignature 1
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanworkstation\parameters\requiresecuritysignature 0
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters\enablesecuritysignature 1
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters\requiresecuritysignature 0


    log file = /var/log/samba/log.%m
    log level = 1
    passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully*$
    obey pam restrictions = yes
    map to guest = bad user
    encrypt passwords = true
    passwd program = /usr/bin/passwd %u
    passdb backend = tdbsam
    dns proxy = no
    netbios name = Mainframe
    server string = %h server (Samba, Ubuntu)
    default = media
    unix password sync = yes
    workgroup = WORKGROUP
    os level = 20
    security = user
    lanman auth = yes
    syslog = 0
    panic action = /usr/share/samba/panic-action %d
    usershare allow guests = yes
    max log size = 1000
    pam password change = yes

    browseable = yes
    writeable = yes
    path = /data/media
    write list = comma,separated,users
    valid users = comma,separated,users
    force create mode = 777
    force user = a-username
    user = comma,separated,users

"Solved" this by creating a smb user with the same user name I use in Windows 10. And if I set the same password that I use in Windows, samba share does not asks for password. Otherwise, it will ask for password, but I use other user to login into it. OR you can comment the line: map to guest = bad user and it will works fine.

  • Commenting out map to guest = bad user fixed it for me. Thanks! Feb 19, 2015 at 12:47
