This article contains a list of known issues and fixes for the Microsoft OLE DB Driver for SQL Server.
- The driver returns the following error message:
Error loading adal.dll from system directory. Verify that Active Directory Authentication Library for SQL Server is properly installed
. The most likely cause of this error is incorrect bitness ofadal.dll
. It can be caused by the installation of version 19.2.0 of the OLE DB Driver. Version 19.2.0 erroneously places a 64-bit ADAL library into the 32-bit system directory. To resolve this issue, install the OLE DB Driver version 19.3 or higher. It includes ADAL 3.6.1 with the correct bitness. - Currently, MSOLEDBSQL19 prevents the creation of linked servers without encryption and a trusted certificate (a self-signed certificate is insufficient). For more information, see Linked servers.
- Use of MSOLEDBSQL19 within a linked server is only supported on SQL Server 2022 or newer.
