IADsAccessControlList::AddAce 方法 (iads.h)
IADsAccessControlList::AddAce 方法将 IADsAccessControlEntry 对象添加到 IADsAccessControlList 对象。
语法
HRESULT AddAce(
[in] IDispatch *pAccessControlEntry
);
parameters
[in] pAccessControlEntry
指向要添加的 IADsAccessControlEntry 对象的 IDispatch 接口的指针。 此参数不能为 NULL。
返回值
返回标准 HRESULT 值,包括以下内容。
注解
访问控制条目必须按以下顺序显示在安全描述符的访问控制列表中:
- 应用于对象本身的拒绝访问 ACE
- 应用于对象的子级(例如属性集或属性)的拒绝访问 ACE
- 允许访问的 ACE,应用于对象本身
- 应用于对象的子级(例如属性集或属性)的允许访问 ACE
- 所有继承的 ACE
示例
以下 Visual Basic 代码示例演示如何使用 IADsAccessControlList::AddAce 方法将两个 ACE 添加到 ACL。
Const ACL_REVISION_DS = &H4
Dim x as IADs
Dim sd as IADsSecurityDescriptor
Dim Ace1 As new IADsAccessControlEntry
Dim Ace2 As new IADsAccessControlEntry
Dim Dacl As new IADsAccessControlList
On Error GoTo Cleanup
Set x = GetObject("LDAP://OU=Sales,DC=Fabrikam,DC=com")
Set sd = x.Get("ntSecurityDescriptor")
' Add the ACEs to the Discretionary ACL.
Dacl.AclRevision = ACL_REVISION_DS 'DS ACL Revision
' Set up the first ACE.
Ace1.AccessMask = -1 'Full Permission (Allowed)
Ace1.AceType = ADS_ACETYPE_ACCESS_ALLOWED
Ace1.AceFlags = ADS_ACEFLAG_INHERIT_ACE
Ace1.Trustee = "myMachine\Administrator"
' Set up the 2nd ACE.
Ace2.AccessMask = -1 'Full Permission (Denied)
Ace2.AceType = ADS_ACETYPE_ACCESS_DENIED
Ace2.AceFlags = ADS_ACEFLAG_INHERIT_ACE
Ace2.Trustee = "aDomain\aUser"
' Add the ACEs to the Discretionary ACL.
Dacl.AddAce Ace1
Dacl.AddAce Ace2
'Commit the changes.
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 Ace1 = Nothing
Set Ace2 = Nothing
Set Dacl = Nothing
Set x = Nothing
Set sd = Nothing
以下 C++ 代码示例使用 IADsAccessControlList::AddAce 方法将 ACE 添加到 ACL。 添加的 ACE 具有具有完全权限的访问权限。
HRESULT addAceTo(IADsAccessControlList *pAcl)
{
if(!pAcl)
{
return E_FAIL;
}
HRESULT hr = pAcl->put_AclRevision(ACL_REVISION_DS);
if(FAILED(hr))
{
return hr;
}
IADsAccessControlEntry *pAce = NULL;
pAce = createAce(-1, // Full permissions.
ADS_ACETYPE_ACCESS_ALLOWED,
ADS_ACEFLAG_INHERIT_ACE,
CComBSTR("aDomain\\aUser"));
if(!pAce)
{
return E_FAIL;
}
IDispatch *pDisp;
hr = pAce->QueryInterface(IID_IDispatch,(void**)&pDisp);
if(FAILED(hr))
{
pAce->Release();
return hr;
}
hr = pAcl->AddAce(pDisp);
pDisp->Release();
if(pAce) pAce->Release();
if(FAILED(hr))
{
return hr;
}
printf("Ace has been added to ACL.\n");
return hr;
