As we strive to deliver new and innovative products continually, we wish to inform you of the End of Availability (EOA) of the Microsoft NT LAN Manager (NTLM) protocol-based authentication in VMware Identity Manager starting Tuesday, August 22, 2019.
NTLM protocol-based authentication was used to support authentication to older versions of Windows desktops. To enable Integrated Windows Authentication (IWA) authenticating against an Active Directory infrastructure that relies on NTLM based authentication.
At this time VMware Identity Manager extends support for Windows Server 2008, 2012, and 2016 which offer Kerberos based authentication which makes the NTLM protocol support to authenticate to Windows servers redundant. Following this end of availability, on October 24, 2019, the NTLM protocol-based authentication will be deprecated and will no longer be available in VMware Identity Manager.
On August 22, 2019, NTLM protocol support in VMware Identity Manager will reach the end of life. Integrated Windows Authentication (IWA) from a Windows desktop against an Active Directory infrastructure will be available through Kerberos. VMware recommends that in preparation for the end of availability on October 24, 2019, any existing desktop devices using Windows which rely on NTLM are upgraded to Windows systems that are compatible with Kerberos based authentication.
