SQL Server mutual authentication(2-way ssl) RRS feed

  • Question

  • Hi all, 

    I am trying to use TLS/SSL with SQL server. I can successfully setup server for 1-way SSL. However, as the next part of my project, I need to implement 2-way SSL also(i.e. need to validate client certificates). I couldn't find any documentation how and if SQL server supports this feature. While browsing, I found this answer https://social.msdn.microsoft.com/Forums/sqlserver/en-US/076e0764-576f-40a9-9bfc-b622e4ac8e22/sql-2014-certificate-authentication?forum=sqlsecurity. Is it still valid for latest versions of SQL server? 

    Is there any official documentation stating that it does not support mutual authentication(if it doesn't)?

    Does anyone have any information regarding this? Thanks

    >> Is it still valid for latest versions of SQL server?

    Yes. As Raul Garcia mentioned, SQL Server supports two authentication modes, Windows authentication mode and mixed mode. Please refer to Authentication in SQL Server.

    I found a similar thread, hope it could help you.

    Best regards,
