Security limitations for SQL Server on Linux

[!INCLUDE SQL Server - Linux]

SQL Server on Linux currently has the following limitations:

  • A standard password policy is provided. MUST_CHANGE is the only option you may configure. CHECK_POLICY option is not supported.
  • Extensible Key Management is not supported.
  • SQL Server Authentication mode cannot be disabled.
  • Using keys stored in the Azure Key Vault is not supported.
  • SQL Server generates its own self-signed certificate for encrypting connections. SQL Server can be configured to use a user provided certificate for TLS.

For more information about security features available in SQL Server, see the Security Center for SQL Server Database Engine and Azure SQL Database.
