![]() See description of Authentication keyword above. SQL_AU_NONE, SQL_AU_PASSWORD, SQL_AU_AD_INTEGRATED, SQL_AU_AD_PASSWORD, SQL_AU_AD_INTERACTIVE, SQL_AU_AD_MSI, SQL_AU_AD_SPA, SQL_AU_RESET When a connection attribute has a corresponding connection string or DSN keyword and is set, the connection attribute takes precedence. The following pre-connect connection attributes have either been introduced or modified to support Azure Active Directory authentication. New and/or Modified Connection Attributes The pre-attribute value of Encryption is Yes if the value is set to Yes in either the DSN or connection string. If the attribute SQL_COPT_SS_AUTHENTICATION overrides the pre-attribute value of Authentication, explicitly set the value of Encryption in the DSN or connection string or connection attribute. ![]() The default is also Yes in versions 18.0.1+. If the pre-attribute value of the Authentication setting is not none in the DSN or connection string, the default is Yes. (not set), Yes/ Mandatory(18.0+), No/ Optional(18.0+), Strict(18.0+)Ĭontrols encryption for a connection. UID is set to the client ID of the service principal. (17.7+) Authenticate with Azure Active Directory identity using service principal authentication. For user-assigned identity, UID is set to the object ID of the user identity.

The pre-attribute value of the Authentication setting is the value computed from the connection string and DSN values. The value set in the connection string overrides that in the DSN, if provided. The Authentication keyword can be used when connecting with a DSN or connection string to control the authentication mode. New and/or Modified DSN and Connection String Keywords As of driver version 17.6, this limitation has been removed. If you are using Azure Active Directory username/password authentication from a Linux or macOS client and your Active Directory configuration requires the client to authenticate against an Active Directory Federation Services endpoint, authentication may fail. The ODBC Driver on Linux and macOS before version 17.6 only supports Azure Active Directory authentication directly against Azure Active Directory. For more information, see Configure and manage Azure AD authentication with Azure SQL. ![]() To use Azure Active Directory authentication, you must configure your Azure SQL data source. All of these options are accomplished by using new DSN and connection string keywords, and connection attributes. A new Azure Active Directory managed identity authentication method was added in ODBC Driver version 17.3.1.1 for both system-assigned and user-assigned identities. A new Azure Active Directory interactive authentication with Login ID is introduced in ODBC Driver version 17.1 for Windows. The ODBC Driver version 17 and above support this authentication across all platforms (Windows, Linux, and macOS). For the ODBC Driver version 13.1, the Azure Active Directory access token authentication is Windows only. The identity can use a username/password, an Azure Active Directory access token, an Azure Active Directory managed identity (17.3+), or Windows-Integrated Authentication (17.6+ on Linux/macOS). The Microsoft ODBC Driver for SQL Server version 13.1 or above allows ODBC applications to connect to an instance of Azure SQL Database using a federated identity in Azure Active Directory.
