SpLsaModeInitialize function

The SpLsaModeInitialize function is called once by the Local Security Authority (LSA) for each registered security support provider/authentication package (SSP/AP) DLL it loads. This function provides the LSA with pointers to the functions implemented by each security package in the SSP/AP DLL.


NTSTATUS NTAPI SpLsaModeInitialize(
  _In_  ULONG                  LsaVersion,
  _Out_ PULONG                 PackageVersion,
  _Out_ PULONG                 pcTables


LsaVersion [in]

The version of the LSA.

PackageVersion [out]

Pointer to a ULONG that returns the SSP/AP DLL version number.

ppTables [out]

Pointer to an array of SECPKG_FUNCTION_TABLE structures. Each structure is a table of pointers to the functions implemented by a security package deployed in the SSP/AP DLL.

pcTables [out]

Pointer that returns the number of elements in the array pointed to by the ppTables parameter.

Return value

If the function succeeds, return STATUS_SUCCESS.

If the function fails, return an NTSTATUS code that indicates the reason it failed.


The SpLsaModeInitialize function must be implemented by SSP/AP DLLs.

The ppTables parameter should contain one SECPKG_FUNCTION_TABLE for each security package deployed in the DLL.
