TRUSTEE

[New - Windows NT]

The TRUSTEE structure identifies a user account, group account, or a logon account for a program such as a Windows NT service. The structure can use a name or a security identifier (SID) to identify the trustee.

Access control functions, such as SetEntriesInAcl and GetExplicitEntriesFromAcl, use this structure to identify the logon account associated with the access-control or audit-control information in an EXPLICIT_ACCESS structure.

typedef struct _TRUSTEE

{

PTRUSTEE pMultipleTrustee;

MULTIPLE_TRUSTEE_OPERATION MultipleTrusteeOperation;

TRUSTEE_FORM TrusteeForm;

TRUSTEE_TYPE TrusteeType;

LPTSTR ptstrName;

} TRUSTEE;

Members

pMultipleTrustee

Pointer to a TRUSTEE structure that identifies a server account that can impersonate the user identified by the ptstrName member. Windows NT does not currently support this functionality; therefore, this member must be NULL.

MultipleTrusteeOperation

Specifies a value from the MULTIPLE_TRUSTEE_OPERATION enumeration type. Currently, this member must be NO_MULTIPLE_TRUSTEE.

TrusteeForm

Specifies a value from the TRUSTEE_FORM enumeration type that indicates whether the trustee is identified by name or by a SID.

TrusteeType

Specifies a value from the TRUSTEE_TYPE enumeration type that indicates whether the trustee is a user account, a group account, or the account type is unknown.

ptstrName

If TrusteeForm is TRUSTEE_IS_NAME, this member is a pointer to a null-terminated string that contains the name of the trustee.

If TrusteeForm is TRUSTEE_IS_SID, this member is a pointer to the SID of the trustee.

Remarks

A trustee name can have any of the following formats:

·A fully qualified name, such as "g:\remotedir\abc".

·A Windows NT version 3.x or later domain account, such as "redmond\xyz".

·One of the predefined group names, such as "EVERYONE" or "GUEST".

·One of the following special names.

Name Meaning
"CURRENT_USER" Indicates the owner of the calling thread or process.
"CREATOR OWNER" Indicates the CREATOR_OWNER security identifier. This is a SID used in inheritable ACEs. When a new object is created, the system replaces this SID with the SID of the user who created the object.
"CREATOR GROUP" Indicates the CREATOR_GROUP security identifier. This is a SID used in inheritable ACEs. When a new object is created, the system replaces this SID with the primary group SID of the user who created the object.

A trustee SID can be any user or group SID. It can also be any of the universal, well-known SIDs. For more information, see Security Identifiers (SIDs).
