Users can no longer login to RHEL 6 systems using their Windows AD account after SMB1 has been disabled in Active-Directory.
Issue
1. 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.
2. When 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
