LSA_AP_CALL_PACKAGE_PASSTHROUGH callback function (ntsecpkg.h)

  • Article

The dispatch function for pass-through logon requests sent to the LsaCallAuthenticationPackage function.

Syntax

LSA_AP_CALL_PACKAGE_PASSTHROUGH LsaApCallPackagePassthrough;

NTSTATUS LsaApCallPackagePassthrough(
  [in]  PLSA_CLIENT_REQUEST ClientRequest,
  [in]  PVOID ProtocolSubmitBuffer,
  [in]  PVOID ClientBufferBase,
  [in]  ULONG SubmitBufferLength,
  [out] PVOID *ProtocolReturnBuffer,
  [out] PULONG ReturnBufferLength,
  [out] PNTSTATUS ProtocolStatus
)
{...}

Parameters

[in] ClientRequest

Pointer to an opaque LSA_CLIENT_REQUEST buffer representing the LSA client's request.

[in] ProtocolSubmitBuffer

Supplies a protocol-specific message to the authentication package.

[in] ClientBufferBase

Provides the address within the client process of the protocol message. This may be necessary to remap pointers within the ProtocolSubmitBuffer.

[in] SubmitBufferLength

Specifies the length of the ProtocolSubmitBuffer buffer, in bytes.

[out] ProtocolReturnBuffer

Returns the address of the output buffer in the client process. The authentication package is responsible for calling the AllocateClientBuffer function to allocate the buffer in the client process. The contents of this buffer are specific to the authentication package.

[out] ReturnBufferLength

Pointer to a ULONG that returns the length of the ProtocolReturnBuffer buffer, in bytes.

[out] ProtocolStatus

Pointer to an NTSTATUS value. If the function returns STATUS_SUCCESS, ProtocolStatus returns a completion status set by the authentication package. ProtocolStatus values are specific to the authentication package.

More information about NTSTATUS codes can be found in the Subauth.h file shipped with the Platform SDK.

Return value

If the function succeeds, return STATUS_SUCCESS. This return value indicates that the authentication package attempted to provide the requested service. Use the ProtocolStatus parameter to return the completion status of the service request.

If the authentication package could not process the request and therefore did not attempt to provide the requested service, return an NTSTATUS code indicating the problem. This code can be the following value or one of the LSA Policy Function Return Values.

Return code Description
STATUS_NO_MEMORY
 The client's memory quota is insufficient to allocate the output buffer.

Remarks

This function must be implemented by authentication packages.
