The SpShutDown function is called by the Local Security Authority (LSA) before the security support provider/authentication package (SSP/AP) is unloaded. The implementation of this function should release any allocated resources, such as credentials.
This function has no parameters.
If the function succeeds, return STATUS_SUCCESS.
If the function fails, return an NTSTATUS code that indicates the reason it failed.
SSP/APs must implement the SpShutDown function; however, the actual name given to the implementation is up to the developer.
