GetObject IADs

[Jean-Marc Autexier]

Hi, 

I'm trying to read AD/LDAP user information using the windows API (I don't want to authenticatite to LDAP). 

I've generated ADO classes an can retrieve user information with the following code: 

String defaultNamingContext = "DC=DE,DC=xxx,DC=xxx,DC=xxxx";

String username = "userName you want to query";

_Connection c = Connection.create(ClsCtx.SERVER);

c.setProvider(new BStr("ADsDSOObject"));

c.open();

msado.adodb._Command command = msado.adodb.Command.create(ClsCtx.SERVER);

command.setActiveConnectionByRef(c);

String requestedInfo = "givenName,sn,userPrincipalName,telephoneNumber,mail,HomeDirectory,streetAddress,department,company,title,manager,l,c,telephoneNumber,facsimileTelephoneNumber,location";

String query = "<LDAP://" + defaultNamingContext + ">;(sAMAccountName=" + username + ");" + requestedInfo + ";subTree";

command.setCommandText(new BStr(query));

_Recordset recordSet = command.execute(new Variant(), Variant.createUnspecifiedParameter(), new Int32(-1));

Fields userData = recordSet.getFields();

StringTokenizer tokenizer = new StringTokenizer(requestedInfo, ",");

while (tokenizer.hasMoreTokens()) {

   String currentFieldStr = tokenizer.nextToken();

   Field currentField = userData.getItem(new Variant(currentFieldStr));

   System.out.println(currentFieldStr +" : "+currentField.getValue().getBstrVal());

}

What I don't know is how to get the defaultNamingContext and the current user which is logged in. 

For the current user, I could use environment properties, but I would like to use the windows API as well. 

From vairous C#/C++/.. samples I know I have to use IADs object and "get" the defaultnaming context. Something like (VB Code): 

Dim rootDSE As IADs
Dim defaultNamingContext As String
 
Set rootDSE = GetObject("LDAP://rootDSE")
defaultNamingContext = rootDSE.Get("defaultNamingContext")

Source: http://msdn.microsoft.com/en-us/library/ms676736(v=vs.85).aspx 

But how can I get an IADs object instance? 

Can you help?

Update

I found on way to do it, but it's probably not the most elegant: from I can get the computer name, an dfrom it I cn extract the "defaultNamingContext" by parsing the String. 

IADsADSystemInfo info = ADSystemInfo.create(ClsCtx.SERVER) ;

String computername = info.getComputerName().toString() ;

int start = computername.indexOf("DC=") ;

defaultNamingContext = computername.substring(start, computername.length()) ;

This returns something like"DC=DE,DC=xxxx,DC=xxxxx,DC=xxxxx"

Hi,

I'm still looking for a solution:

How can I instantiate with ComfyJ an objekt IADs with those parameters? Here is the C++ code:

IADs *pads;
hr = ADsGetObject(  L"LDAP://rootDSE",IID_IADs, (void**)&pads);

Hi Jean-Marc,

As a straightforward solution, you can load the function and invoke it in your code with appropriate parameters.

The general idea is shown below:

        Library activeDS = new Library("Activeds");
        activeDS.load();

        Function adsGetObject = activeDS.getFunction("ADsGetObject");

        HResult result = new HResult();
        BStr lpszPathName = new BStr("LDAP://rootDSE");
        IADs pReqInterface = new IADsImpl();

        Pointer.Const refiid = new Pointer.Const(new IID(IADs.INTERFACE_IDENTIFIER));
        Pointer.OutOnly ppObject = new Pointer.OutOnly((Parameter)pReqInterface);
        adsGetObject.invoke(result, lpszPathName,refiid, ppObject);

You can use the ComException.checkResult() method to check the result value.

Sincerely,
Anna

Hi Jean-Marc,

You can use pReqInterface object after the successful call, there is no need to get the referenced object from the pointer.

Anna
