IADsAccessControlEntry Property Methods

  • Článek

The property methods of the IADsAccessControlEntry interface get or set the properties described in the following table. For more information, see Interface Property Methods.

Properties

AccessMask

Contains a set of flags that specifies access privileges for the object. Valid values for Active Directory objects are defined in the ADS_RIGHTS_ENUM enumeration.

For more information and a list of possible values for file or file share objects, see File Security and Access Rights.

For more information and a list of possible values for registry objects, see Registry Key Security and Access Rights.

Access type: Read/write

Scripting data type: LONG

// C++ method syntax
HRESULT get_AccessMask(
  [out] LONG* plnAccessMask
);
HRESULT put_AccessMask(
  [in] LONG lnAccessMask
);

AceFlags

Contains a set of flags that specifies if other containers or objects can inherit the ACE. Valid values for Active Directory object are defined in the ADS_ACEFLAG_ENUM enumeration.

For more information and possible values for file, file share, and registry objects, see the AceFlags member of the ACE_HEADER structure.

Access type: Read/write

Scripting data type: LONG

// C++ method syntax
HRESULT get_AceFlags(
  [out] LONG* plnAceFlags
);
HRESULT put_AceFlags(
  [in] LONG lnAceFlags
);

AceType

Contains a value that indicates the type of ACE. Valid values for Active Directory objects are defined in the ADS_ACETYPE_ENUM enumeration.

For more information and possible values for file, file share, and registry objects, see the AceType member of the ACE_HEADER structure.

Access type: Read/write

Scripting data type: LONG

// C++ method syntax
HRESULT get_AceType(
  [out] LONG* plAceType
);
HRESULT put_AceType(
  [in] LONG lnAceType
);

Flags

A flag that indicates if the ACE has an object type or inherited object type. Valid flags are defined in the ADS_FLAGTYPE_ENUM enumeration.

Access type: Read/write

Scripting data type: LONG

// C++ method syntax
HRESULT get_Flags(
  [out] LONG* lnflags
);
HRESULT put_Flags(
  [in] LONG lnflags
);

InheritedObjectType

A flag that indicates the type of a child object of an ADSI object. Its value is a GUID to an object in string format. When such a GUID is set, the ACE applies only to the object referred to by the GUID.

Access type: Read/write

Scripting data type: BSTR

// C++ method syntax
HRESULT get_InheritedObjectType(
  [out] BSTR* bstrInheritedObjectType
);
HRESULT put_InheritedObjectType(
  [in] BSTR bstrInheritedObjectType
);

ObjectType

A flag that indicates the ADSI object type. Its value is a GUID to a property or an object in string format. The GUID refers to a property when ADS_RIGHT_DS_READ_PROP and ADS_RIGHT_DS_WRITE_PROP access masks are used. The GUID specifies an object when ADS_RIGHT_DS_CREATE_CHILD and ADS_RIGHT_DS_DELETE_CHILD access masks are used.

Access type: Read/write

Scripting data type: BSTR

// C++ method syntax
HRESULT get_ObjectType(
  [out] BSTR* bstrObjectType
);
HRESULT put_ObjectType(
  [in] BSTR bstrObjectType
);

Trustee

Contains the name of the account that the ACE applies to.

Access type: Read/write

Scripting data type: BSTR

// C++ method syntax
HRESULT get_Trustee(
  [out] BSTR* pbstrSecurityId
);
HRESULT put_Trustee(
  [in] BSTR bstrSecurityId
);

Examples

The following code example shows how to add entries to a discretionary ACL using the IADsAccessControlEntry property methods.

Dim x As IADs
Dim sd As IADsSecurityDescriptor
Dim ace As IADsAccessControlEntry
Dim Dacl As IADsAccessControlList
Dim Ace1 As New AccessControlEntry
Dim Ace2 As New AccessControlEntry

On Error GoTo Cleanup
 
Set x = GetObject("LDAP://OU=Sales, DC=Fabrikam,DC=com")
Set sd = x.Get("ntSecurityDescriptor")
Set Dacl = sd.DiscretionaryAcl
 
' Show the existing ACEs.
For Each ace In Dacl
  Debug.Print ace.Trustee
Next
 
 
' Setup the first ACE.
Ace1.AccessMask = -1 'Full Permission (Allowed)
Ace1.AceType = ADS_ACETYPE_ACCESS_ALLOWED
Ace1.AceFlags = ADS_ACEFLAG_INHERIT_ACE
Ace1.Trustee = "ACTIVED\Administrator"
 
' Setup the 2nd ACE.
Ace2.AccessMask = -1 'Full Permission (Denied)
Ace2.AceType = ADS_ACETYPE_ACCESS_DENIED
Ace2.AceFlags = ADS_ACEFLAG_INHERIT_ACE
Ace2.Trustee = "ACTIVED\Andyhar"
 
' Add the ACEs to the Discretionary ACL.
Dacl.AddAce Ace1
Dacl.AddAce Ace2
 
sd.DiscretionaryAcl = Dacl
x.Put "ntSecurityDescriptor", Array(sd)
x.SetInfo

Cleanup:
    If (Err.Number<>0) Then
        MsgBox("An error has occurred. " & Err.Number)
    End If

    Set x = Nothing
    Set sd = Nothing
    Set ace = Nothing
    Set Dacl = Nothing
    Set Ace1 = Nothing
    Set Ace2 = Nothing
    Set obj = Nothing
    Set cls = Nothing
