/*++

Routine Description:

    This routine is called from the LSA client stubs when
    it is necessary to bind to the LSA on some server.

Arguments:

    ServerName - A pointer to a string containing the name of the server
        to bind with.

Return Value:

    The binding handle is returned to the stub routine.  If the
    binding is unsuccessful, a NULL will be returned.

Routine Description:

    environment.

Arguments:

    Status - The status code to be mapped

Return Value:

    The return from RtlNtStatusToDosError.  If the error could not be
    mapped, then ERROR_MR_MID_NOT_FOUND is returned.

Routine Description:

    This function converts an exception code or status value returned
    from the client stub to a value suitable for return by the API to
    the client.

Arguments:

    ExceptionCode - The exception code to be converted.

Return Value:

    NTSTATUS - The converted Nt Status code.
