We have upgrade our windows server 2008 domain to 2016 version. Now identity engine won't connect to active directory on windows server 2016. We are running identity engine 9.0.3. See snapshot for the error message.
Identity Engines 22.214.171.124 uses SMBv1 as the transport protocol which by default will be disabled on Windows Server 2016 deployments. Additionally Ignition 126.96.36.199 uses either the service account OR anonymous NTLM bindings (depending on configuration) - both of which are also disabled by default with Windows Server 2016.
Upgrade to Ignition 9.3.3 for the best 'baseline' support for Windows Server 2008 / 2012 / 2016.
