We suggest you upgrade your Azure AD Connect server to Windows Server 2019, which is the most recent version of the Windows Server operating system. You can't install this version on an older Windows Server version. Since Azure AD Connect v2 contains SQL Server 2019 components, we no longer can support older Windows Server versions. SQL Server 2019 requires Windows Server 2016 or newer as a server operating system. Windows Server 2012 and Windows Server 2012 R2 are no longer supported There is no action needed from your side. Because of weaknesses in the SHA-1 algorithm and to align to industry standards, we've changed the signing of Windows updates to use the more secure SHA-2 algorithm." The digital signatures are used to ensure that the updates come directly from Microsoft and were not tampered with during delivery. We no longer support SHA1 for downloadable binaries and we upgraded all binaries to SHA2 signing. We noticed that some components had SHA1 signed binaries. For more information, see TLS 1.2 enforcement for Azure AD Connect. If your server doesn't support TLS 1.2 you will need to enable this before you can deploy Azure AD Connect V2.


This release of Azure AD Connect will only support TLS 1.2.Īll versions of Windows Server that are supported for Azure AD Connect V2 already default to TLS 1.2. TLS1.0 and TLS 1.1 are protocols that are deemed unsafe and are being deprecated by Microsoft. This Redistributable will be installed with the Azure AD Connect V2 package, so you don't have to take any action for the C++ runtime update. SQL Server 2019 requires the Visual C++ Redist 14 runtime, so we're updating the C++ runtime library to use this version. For more information, see Overview of the MSAL library. The V2 release ships with the newer MSAL library. This library will be deprecated after December 2022. The previous versions of Azure AD Connect shipped with the ADAL authentication library. For more information, see Microsoft SQL 2019. SQL Server 2012 will go out of extended support in July 2022. V2.0 ships with a SQL Server 2019 LocalDB, which promises enhanced stability and performance and has several security-related bug fixes.

The previous versions of Azure AD Connect shipped with a SQL Server 2012 LocalDB. What are the major changes? SQL Server 2019 LocalDB

If you are still using a Azure AD Connect V1 you need to upgrade to Azure AD Connect V2 immediately. Azure AD Connect V1 installations may stop working unexpectedly. Azure AD Connect V1 has been retired as of Augand is no longer supported.
