writing c# code to get info from LDAP

Hi

I wrote an intranet, and now they want to pull the correct phone numbers for employee's from Active directory via LDAP

I've never used LDAP before, and the Networking department are a pain in the butt to work with, they never help and are always block things

What sort of questions do I need to be asking, or areas to be looking into before starting?
Any advice appreciated to get me upto speed

Thanks

Sample Code :

provide your
LDAP_Server_URL ,
ExportAttributes tags
,FilterValue

//  *************************************************
//          Setting connection to LDAP Server
//  *************************************************
try {
    q = "";
strScope="Subtree";

    cmd = CreateObject("ADODB.Command");
    cn = CreateObject("ADODB.Connection");
    rs = CreateObject("ADODB.Recordset");
    cn.open("Provider=ADsDSOObject;");
    cmd.activeconnection = cn;
    if ((strRoot == "")) {
        objRoot = GetObject(LDAP_Server_URL);
        strRoot = objRoot.GET("defaultNamingContext");
    }
    cmd.commandtext = ("<LDAP://" 
                + (strRoot + (">;" 
                + (strFilter + (";" 
                + (strAttributes + (";" + strScope)))))));
    cmd.properties["page size"] = 1000;
    rs = cmd.EXECUTE;
}
catch (Exception ex) {
    Console.WriteLine("Error in setting Active Directory Connection and Command....Press any key to quit");
    Console.ReadLine();
    return;
}

Open in new window



rs will contain all tags as you set in "strAttributes "...put that into datatable and read them one by one
