Users can no longer login to Linux systems using their Windows AD account after SMB1 has been disabled in Active-Directory.

Solution In Progress - Updated -

Issue

  • As a result of the WannaCrypt ransomware threat, we disabled the SMB1 protocol in our Windows Active-Directory environment. After the change, users were not able to login to Linux-Systems using their Windows AD account.

  • Also joining new systems into the Active-Directory domain does not work anymore and fails with the error NT_STATUS_CONNECTION_RESET.

Environment

  • Red Hat Enterprise Linux 5
  • Red Hat Enterprise Linux 6
  • Samba-3.x with Winbind enrolled into a Windows AD domain
