How to invoke certificate Based Logon using LsaLogonUser?

Hi

How to use LsaLogonUser to invoke Certificate Based Logon. From certain Newsgroups, we have found that if we provide an undocumented structure called KERB_SMART_CARD_LOGON to LsaLogonUser, we can invoke Certificate Based Logon via LsaLogonUser. The structure KERB_SMART_CARD_LOGON is documented in Ntsecapi.h as

typedef struct _KERB_SMART_CARD_LOGON {

KERB_LOGON_SUBMIT_TYPE MessageType;

UNICODE_STRING Pin;

ULONG CspDataLength;

PUCHAR CspData;

} KERB_SMART_CARD_LOGON, *PKERB_SMART_CARD_LOGON;

Now, we could like to know what is the value to be passed to the attribute "CspData" of the structure KERB_SMART_CARD_LOGON?

Thanx in advance,
