Property Value

A value of the LONG* (int, for a .NET application) type. The value maps into a member or a bit-wise combination of some members of the UCC_AUTHENTICATION_MODES enumeration.

Valid authentication modes are defined in the UCC_AUTHENTICATION_MODES enumeration type. The UCC API chooses one of the allowed authentication modes to match the strongest authentication protocol the server uses in the challenge. When a failure occurs, the UCC API does not automatically fall back to a lesser secure authentication mode. The application can choose to fall back to a lesser secure authentication mode by excluding the bit of the higher authentication mode from the allowed authentication modes bitmap.

Win32 COM/C++ Syntax

HRESULT get_AllowedAuthenticationModes
   LONG* plModes
HRESULT put_AllowedAuthenticationModes
   LONG plModes
In a Win32 application, the return value of a method or property is always an HRESULT value indicating the status of the call to the interface member. Any result of the operation is returned as a parameter marked with the [out, retval] attribute. In contrast, in a .NET application the HRESULT value indicating an error condition is returned as a COM exception and the [out, retval] parameter becomes the return value. For the UCC API-defined HRESULT values, see Error Codes.

All public static (Shared in Visual Basic) members of this type are thread-safe. Instance members are not guaranteed to be thread-safe.
