The NETLOGON_VALIDATION_SAM_INFO structure defines account information retrieved from a database upon a successful user logon validation.

All fields of this structure, except the fields detailed following the structure definition, have the same meaning as the identically named fields in the KERB_VALIDATION_INFO structure, as specified in [MS-PAC] section 2.5. Additionally, fields of this structure that are defined as OLD_LARGE_INTEGER [MSDN-OLI] are 64-bit timestamps equivalent to the identically named fields in the KERB_VALIDATION_INFO structure of FILETIME type ([MS-DTYP] section 2.3.3). For more information see [MSDN-FILETIME].

LogonServer: An RPC_UNICODE_STRING structure (defined in [MS-DTYP] section 2.3.10) that contains the NetBIOS name of the server that populates this structure.

ExpansionRoom: A ten-element array of unsigned 32-bit integers. This member has a function similar to that of dummy fields, as detailed in section 1.3.8.1.2. Each element of the array MUST be zero when sent and MUST be ignored on receipt.
