SID_AND_ATTRIBUTES

The SID_AND_ATTRIBUTES structure represents a security identifier (SID) and its attributes. SIDs are used to uniquely identify users or groups.

typedef struct _SID_AND_ATTRIBUTES { 
  PSID  Sid; 
  DWORD Attributes; 
} SID_AND_ATTRIBUTES, *PSID_AND_ATTRIBUTES; 

Members

Sid

Pointer to a SID structure.

Attributes

Specifies attributes of the SID. This value contains up to 32 one-bit flags. Its meaning depends on the definition and use of the SID.

Remarks

A group is represented by a SID. SIDs have attributes that indicate whether they are currently enabled, disabled, or mandatory, and how they are used. A SID_AND_ATTRIBUTES structure can represent a SID whose attributes change frequently. For example, it is used to represent groups in the TOKEN_GROUPS structure.

Requirements

  Windows NT/2000: Requires Windows NT 3.1 or later.
  Header: Declared in Winnt.h; include Windows.h.
