IADsAccessControlList::CopyAccessList method (iads.h)

The IADsAccessControlList::CopyAccessList method copies every access control entry (ACE) in the access-control list (ACL) to the caller's process space.

Syntax

HRESULT CopyAccessList(
  [out] IDispatch **ppAccessControlList
);

Parameters

[out] ppAccessControlList

Address of an IDispatch interface pointer to an ACL as the copy of the original access list. If this parameter is NULL on return, no copies of the ACL could be made.

Return value

This method returns the standard return values.

For more information about other return values, see ADSI Error Codes.

Remarks

The caller must call Release on the copy of ACEs through their IDispatch pointers.

Examples

The following code example shows how to copy an ACL from one ADSI object to another.

Dim x As IADs
Dim sd As IADsSecurityDescriptor
Dim Dacl As IADsAccessControlList
Dim CopyDacl As IADsAccessControlList
 
' Get the ACL from one object.
Set x = GetObject("LDAP://OU=Sales, DC=activeD,DC=mydomain,DC=fabrikam,DC=com")
Set sd = x.Get("ntSecurityDescriptor")
Set Dacl = sd.DiscretionaryAcl
Set CopyDacl = Dacl.CopyAccessList()
 
' Copy the ACL to another object in the Directory.
Set x = GetObject("LDAP://OU=Sales, DC=Fabrikam,DC=com")
Set sd = x.Get("ntSecurityDescriptor")
sd.DiscretionaryAcl = CopyDacl
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 Dacl = Nothing
    Set CopyDacl = Nothing

The following code example copies the ACL from the source object to the target object.

HRESULT CopyACL(IADs *pSource, IADs *pTarget)
{
    IADsSecurityDescriptor *pSourceSD = NULL;
    IADsSecurityDescriptor *pTargetSD = NULL;    
    IDispatch *pDisp = NULL;
    
    HRESULT hr = S_OK;
    VARIANT varSource, varTarget;
    
    VariantInit(&varSource);
    VariantInit(&varTarget);

    if((pSource==NULL) || (pTarget==NULL))
    {
        return E_FAIL;
    }
    
    hr = pSource->Get(CComBSTR("ntSecurityDescriptor"), &varSource);
    if(FAILED(hr))
    {
        goto Cleanup;
    }
    
    hr = pTarget->Get(CComBSTR("ntSecurityDescriptor"), &varTarget);
    if(FAILED(hr))
    {
        goto Cleanup;
    }
    
    hr = V_DISPATCH(&varSource)->QueryInterface(IID_IADsSecurityDescriptor,
                    (void**)&pSourceSD);
    if(FAILED(hr))
    {
        goto Cleanup;
    }    

    hr = V_DISPATCH(&varTarget)->QueryInterface(IID_IADsSecurityDescriptor,
                    (void**)&pTargetSD);
    if(FAILED(hr))
    {
        goto Cleanup;
    }    
    
    hr = pSourceSD->get_DiscretionaryAcl(&pDisp);
    if(FAILED(hr))
    {
        goto Cleanup;
    }    

    hr = pTargetSD->put_DiscretionaryAcl(pDisp);
    if(FAILED(hr))
    {
        goto Cleanup;
    }    
    
    hr = pTarget->SetInfo();
        
Cleanup:
    VariantClear(&varSource);
    VariantClear(&varTarget);
    if(pSourceSD) 
    {
        pSourceSD->Release();
    }
    if(pTargetSD) 
    {
        pTargetSD->Release();
    }
    if(pDisp) 
    {
        pDisp->Release();
    }
    return hr;
}
