RADIUS_ATTRIBUTE structure (authif.h)
Note Internet Authentication Service (IAS) was renamed Network Policy Server (NPS) starting with Windows Server 2008. The content of this topic applies to both IAS and NPS.
Syntax
typedef struct _RADIUS_ATTRIBUTE {
DWORD dwAttrType;
RADIUS_DATA_TYPE fDataType;
DWORD cbDataLength;
union {
DWORD dwValue;
const BYTE *lpValue;
};
} RADIUS_ATTRIBUTE, *PRADIUS_ATTRIBUTE;
Members
dwAttrType
Stores a value from the RADIUS_ATTRIBUTE_TYPE enumeration. This value specifies the type of the attribute represented by the RADIUS_ATTRIBUTE structure.
fDataType
Stores a value from the RADIUS_DATA_TYPE enumeration. This value specifies the type of the value stored in the union that contains the dwValue and lpValue members.
cbDataLength
Stores the length, in bytes, of the data. The cbDataLength member is used only if lpValue member is used.
dwValue
Stores a value of type DWORD. The dwValue member is used if the fDataType member specifies rdtAddress, rdtInteger, or rdtTime.
Note In Windows Server 2008 the byte order format of dwValue is represented in network byte order (big-endian) when fDataType is specified as rdtAddress. Previous Windows versions represented network addressing using the little-endian format.
lpValue
Stores a multi-byte data value. The lpValue member is used if the fDataType member specifies rdtUnknown, rdtIpv6Address, or rdtString.
