When a connection is opened, [!INCLUDEssNoVersion] Native Client sets SQL_COPT_SS_MUTUALLY_AUTHENTICATED and SQL_COPT_SS_INTEGRATED_AUTHENTICATION_METHOD to the authentication method used to open the connection. For more information about SPNs, see Service Principal Names (SPNs) in Client Connections (ODBC).
For more information on using SQLConnect to connect to a [!INCLUDEssHADR] cluster, see SQL Server Native Client Support for High Availability, Disaster Recovery.
