SID_AND_ATTRIBUTES structure (ntifs.h)

  • Article

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

Syntax

typedef struct _SID_AND_ATTRIBUTES {
#if ...
  PISID Sid;
#else
  PSID  Sid;
#endif
  ULONG 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.
