2.2.1 KERB_SID_AND_ATTRIBUTES

  • Article

The KERB_SID_AND_ATTRIBUTES structure represents a SID and its attributes for use in authentication. It is sent within the KERB_VALIDATION_INFO (section 2.5) structure and used to include additional information about the group that the SID references.

The KERB_SID_AND_ATTRIBUTES structure is defined as follows.

 typedef struct _KERB_SID_AND_ATTRIBUTES {
     PISID Sid;
     ULONG Attributes;
 } KERB_SID_AND_ATTRIBUTES, *PKERB_SID_AND_ATTRIBUTES;

Sid: A pointer to an RPC_SID structure ([MS-DTYP] section 2.4.2.3).

Attributes: A set of bit flags that describe attributes of the SID in the Sid field.

Attributes can contain one or more of the following bits.
