This property specifies whether to connect to the Microsoft Active Directory when the connection is opened.
When set to true, a connection will be made to Microsoft Active Directory when the connection is opened. This property enables the Test Connection feature available in various database tools.
This feature acts as a NOOP command as it is used to verify a connection can be made to Microsoft Active Directory and nothing from this initial connection is maintained.
Setting this property to false may provide performance improvements (depending upon the number of times a connection is opened).
