Hi All,

The last few posts I’ve posted used the SQL syntax method to query Active Directory.
This is different to my previous posts where I was using the IADs interface.
With the IADs interface, we would bind to an object and query it that way, with ActiveX Data Objects, we use SQL-like syntax to query Active Directory

This codeblock below will select all users from the domain.


objRootDSE = GetObject("LDAP://RootDSE");
strDomain = objRootDSE.Get("DefaultNamingContext");
/*This gets the Default Naming context, i.e. the domain root*/

objConnection = new ActiveXObject("ADODB.Connection");
objConnection.Provider="ADsDSOObject";
objConnection.Open("ADs Provider");
objCommand = new ActiveXObject("ADODB.Command");
objCommand.ActiveConnection = objConnection;

/*This sets up the Connection to AD, sets the provider to ADsDSOObject, and creates an object that we can use to execute a command*/

var strDom = "LDAP://"+strDomain;
/* The strDom string will later become part of the SQL command that we will execute. If you want to specify a OU or CN to search, here would be the place to put it. */

objCommand.CommandText = "select name from '"+strDom+" WHERE objectCategory = 'user'';

/* Next up is the command itself.*/

objRecordSet = objCommand.Execute();

/* Then we execute the command */
/* Once executed, the command will return an enumeration of the results.*/
/* We will use the standard JS enumeration methods here to get what we need*/

objRecordSet.Movefirst;
while(!(objRecordSet.EoF)) {
objRecordSet.Fields("name").value; // This will be the fields that you Selected in the command's value, if you've selected more than one then you will need a loop or multiple statements to get it all.
objRecordSet.MoveNext;
}

The codeblock will need modification to suit your needs but it well let you search Active Directory with ease from JScript.
