Develop Reference

a list of all users: Ldap referral error (LDAPReferralException)

I am using active directory and want a list of all users, basically in dotnet core. But I am receiving an exception:
Search result reference received, and referral following is off
Below is my code.
LdapSearchResults lsc = lc.Search("DC = xyz, DC = local", LdapConnection.SCOPE_ONE , "(|(objectClass = person)(objectClass = user))", null, false);

Necromancing - just in case the links go dark.
To fix it in your application, set ReferralFollowing to true.
if you get the message
Search result reference received, and referral following is off
, add
Novell.Directory.Ldap.LdapSearchConstraints cons = lc.SearchConstraints;
cons.ReferralFollowing = true;
lc.Constraints = cons;
to your code.
Example:
public static void GetUsers()
{
System.Collections.Generic.List<ARSoft.Tools.Net.Dns.SrvRecord> lsLdap = GetLdap();
ARSoft.Tools.Net.Dns.SrvRecord ldap = lsLdap[0];
string[] attrs = new string[] { "cn", "distinguishedName", "sAMAccountName", "userPrincipalName", "displayName", "givenName", "sn", "mail", "mailNickname", "memberOf", "homeDirectory", "msExchUserCulture" };
// CN = Common Name
// OU = Organizational Unit
// DC = Domain Component
string searchBase = "DC=cor,DC=local";
string searchFilter = "(&(objectClass=user)(objectCategory=person))";
string ldapHost = MySamples.TestSettings.ldapHost;
int ldapPort = MySamples.TestSettings.ldapPort;//System.Convert.ToInt32(args[1]);
string loginDN = MySamples.TestSettings.loginDN; // args[2];
string password = MySamples.TestSettings.password; // args[3];
Novell.Directory.Ldap.LdapConnection lc = new Novell.Directory.Ldap.LdapConnection();
int ldapVersion = Novell.Directory.Ldap.LdapConnection.Ldap_V3;
try
{
// connect to the server
lc.Connect(ldap.Target.ToString(), ldap.Port);
// bind to the server
lc.Bind(ldapVersion, loginDN, password);
Novell.Directory.Ldap.LdapSearchConstraints cons = lc.SearchConstraints;
cons.ReferralFollowing = true;
lc.Constraints = cons;
// To enable referral following, use LDAPConstraints.setReferralFollowing passing TRUE to enable referrals, or FALSE(default) to disable referrals.
Novell.Directory.Ldap.LdapSearchResults lsc = lc.Search(searchBase,

You have to activate the behaviour which will follow the referral returned by the directory.
The response you received means that the directory you are requesting does not contain the data you look for, but they are in another directory, and in the response there is the information about the "referral" directory on which you need to rebind to "redo" the search. This principle in LDAP are the referral.
I don't know how to do it in C#, but maybe have a look at :

reading messages from fb

I successfully login to facebook but while trying to read the mailbox I got the following error: {"(OAuthException - #298) (#298) Requires extended permission: read_mailbox"}
If I add that scope in the URL;
var destinationUrl =
String.Format(
"https://www.facebook.com/dialog/oauth?client_id={0}&scope={1}&display=popup&redirect_uri=http://www.facebook.com/connect/login_success.html&response_type=token",
AppID, //client_id
"user_posts" //scope
);
and try to get mails:
private void FaceBookScrapper()
{
var client = new FacebookClient(_fbToken);
var input = new List<FbMesseage>();
if (client != null)
{
dynamic result = client.Get("me/inbox", null);
foreach (var item in result.inbox.data)
{
if (item.unread > 0 || item.unseen > 0)
{
foreach (var message in item.comments.data)
{
input.Add(new FbMesseage
{
Id = message.id,
FromName = message.from.name,
FromId = message.from.id,
Text = message.message,
CreatedDate = message.created_time
});
}
FbMesseageCollectionViewModelIns.LoadData(input);
}
}
}
}
}
}

That permission doesn't exist any more - it has been removed, together with the /user/inbox endpoint.
https://developers.facebook.com/docs/apps/changelog#v2_4_deprecations mentions this, and https://developers.facebook.com/docs/graph-api/reference/v2.5/user/inbox as well.
Under the latter URL, it says it right on the very top of the page:
This document refers to a feature that was removed after Graph API v2.4.
There is no way any more to access a user's inbox via API.

Bloomberg web service call for single field and single instrument taking more than 1 min

I am making a Bloomberg web service GetData call for the "DEBT_TO_EQUITY_FUNDAMENTALS_TKR" field. I am setting secmaster = true and asking for a single instrument with a CUSIP identifier (with yellowkey = MarketSector.Corp).
This strikes me as a fairly lightweight call having seen people asking for thousands of instruments and dozens of fields at once.
I have played around with setting lots of different settings but I just can't get this request to return in a few seconds. It gives me the correct return value but it takes longer than 60 seconds.
Any idea if it is possible to get such a request to execute and return in a few seconds?
Thanks
EDIT - Here is the code I am running:
public string GetFundamentalTicker(string identifier, InstrumentType identifierType = InstrumentType.CUSIP)

Poll interval is 5 seconds and the SOAP web service url is:
https://software.bloomberg.com/datalicensewp/dlws.wsdl

I am having the same issue. I found out that there is a difference between making the same call to Bloomberg API from, for example, console app (works very fast) and web service (takes a lot of time to start session). And the difference is that console app runs under the same user as bbcomm process, whereas web service (or actually iis process) runs under System account. You can try to log out all users on the PC where web service is hosted and then try to make the call. In this case, I guess, bbcomm goes under System account as no one else is logged in and works fast. It worked for me and the call was answered instantly.

c# ebay api, works on W7 but not on xp

I developed an application that use the "finditemsAdvanced" api call of ebay.
It works without problem on windows 7 but when i try it on xp machines the function returns null!!!! I tried to debug it on xp, with vs2010 and vs 2008 but nothing!!!!
here the search class:
public SearchResult Search(Job searchedjob)
{
try
{
EbayFind service = new EbayFind();
service.Url = "http://svcs.ebay.com/services/search/FindingService/v1";
FindItemsAdvancedRequest findrequest = new FindItemsAdvancedRequest();
ItemFilter[] filtro = new ItemFilter[1];
int filter = 0;
//Tempo rimanente
filtro[filter] = new ItemFilter();
filtro[filter].name = ItemFilterType.EndTimeTo;
filtro[filter].value = new string[]
{
searchedjob.TimeLeft.ToString("yyyy-MM-ddTHH:mm:ss.000Z")
};
filter++;
findrequest.keywords = "canon";
findrequest.itemFilter = filtro;
findrequest.descriptionSearch = false;
// Setting the pagination
PaginationInput pagination = new PaginationInput();
pagination.entriesPerPageSpecified = true;
pagination.entriesPerPage = 25;
pagination.pageNumberSpecified = true;
pagination.pageNumber = 1;
findrequest.paginationInput = pagination;
findrequest.paginationInput = pagination;
// Creating an object to the BestMatchService class
FindItemsAdvancedResponse resp = service.findItemsAdvanced(findrequest);
SearchResult res = resp.searchResult;
return res;
}
and here the ebay call:
class EbayFind : FindingService
{
protected override System.Net.WebRequest GetWebRequest(Uri uri)
{
try
{
HttpWebRequest request = (HttpWebRequest)base.GetWebRequest(uri);
request.Headers.Add("X-EBAY-SOA-SECURITY-APPNAME", "myappid");
request.Headers.Add("X-EBAY-SOA-OPERATION-NAME", "findItemsAdvanced");
request.Headers.Add("X-EBAY-SOA-SERVICE-NAME", "FindingService");
request.Headers.Add("X-EBAY-SOA-MESSAGE-PROTOCOL", "SOAP11");
request.Headers.Add("X-EBAY-SOA-SERVICE-VERSION", "1.0.0");
request.Headers.Add("X-EBAY-SOA-GLOBAL-ID", "EBAY-US");
return request;
}
catch (Exception ex)
{
throw ex;
}
}
}
This code works on w7 machines, i don't understand why "res" is always null on xp!!!
The net framework installed is 3.5 and 4.0, it's not a framework issue i think.
Any ideas??
Thanks!

Stab in the dark -- Windows Firewall.
Try disabling it in the control panel while debugging. If it makes a difference, configure an exception to allow the api calls from your application through.

Programmatically create a web site in IIS using C# and set port number

We have been able to create a web site. We did this using the information in this link:
https://msdn.microsoft.com/en-us/library/ms525598.aspx
However, we would like to use a port number other that port 80. How do we do this?
We are using IIS 6

If you're using IIS 7, there is a new managed API called Microsoft.Web.Administration
An example from the above blog post:
ServerManager iisManager = new ServerManager();
iisManager.Sites.Add("NewSite", "http", "*:8080:", "d:\\MySite");
iisManager.CommitChanges();
If you're using IIS 6 and want to do this, it's more complex unfortunately.
You will have to create a web service on every server, a web service that handles the creation of a website because direct user impersonation over the network won't work properly (If I recall this correctly).
You will have to use Interop Services and do something similar to this (This example uses two objects, server and site, which are instances of custom classes that store a server's and site's configuration):
string metabasePath = "IIS://" + server.ComputerName + "/W3SVC";
DirectoryEntry w3svc = new DirectoryEntry(metabasePath, server.Username, server.Password);
string serverBindings = ":80:" + site.HostName;
string homeDirectory = server.WWWRootPath + "\\" + site.FolderName;
object[] newSite = new object[] { site.Name, new object[] { serverBindings }, homeDirectory };
object websiteId = (object)w3svc.Invoke("CreateNewSite", newSite);
// Returns the Website ID from the Metabase
int id = (int)websiteId;
See more here

Heres the solution.
Blog article : How to add new website in IIS 7
On Button click :
try
{
ServerManager serverMgr = new ServerManager();
string strWebsitename = txtwebsitename.Text; // abc
string strApplicationPool = "DefaultAppPool"; // set your deafultpool :4.0 in IIS
string strhostname = txthostname.Text; //abc.com
string stripaddress = txtipaddress.Text;// ip address
string bindinginfo = stripaddress + ":80:" + strhostname;
//check if website name already exists in IIS
Boolean bWebsite = IsWebsiteExists(strWebsitename);
if (!bWebsite)
{
Site mySite = serverMgr.Sites.Add(strWebsitename.ToString(), "http", bindinginfo, "C:\\inetpub\\wwwroot\\yourWebsite");
mySite.ApplicationDefaults.ApplicationPoolName = strApplicationPool;
mySite.TraceFailedRequestsLogging.Enabled = true;
mySite.TraceFailedRequestsLogging.Directory = "C:\\inetpub\\customfolder\\site";
serverMgr.CommitChanges();
lblmsg.Text = "New website " + strWebsitename + " added sucessfully";
}
else
{
lblmsg.Text = "Name should be unique, " + strWebsitename + " is already exists. ";
}
}
catch (Exception ae)
{
Response.Redirect(ae.Message);
}
Looping over sites whether name already exists
public bool IsWebsiteExists(string strWebsitename)
{
Boolean flagset = false;
SiteCollection sitecollection = serverMgr.Sites;
foreach (Site site in sitecollection)
{
if (site.Name == strWebsitename.ToString())
{
flagset = true;
break;
}
else
{
flagset = false;
}
}
return flagset;
}

Try the following Code to Know the unUsed PortNo
DirectoryEntry root = new DirectoryEntry("IIS://localhost/W3SVC");
// Find unused ID PortNo for new web site
bool found_valid_port_no = false;
int random_port_no = 1;
do
{
bool regenerate_port_no = false;
System.Random random_generator = new Random();
random_port_no = random_generator.Next(9000,15000);
foreach (DirectoryEntry e in root.Children)
{
if (e.SchemaClassName == "IIsWebServer")
{
int site_id = Convert.ToInt32(e.Name);
//For each detected ID find the port Number
DirectoryEntry vRoot = new DirectoryEntry("IIS://localhost/W3SVC/" + site_id);
PropertyValueCollection pvcServerBindings = vRoot.Properties["serverbindings"];
String bindings = pvcServerBindings.Value.ToString().Replace(":", "");
int port_no = Convert.ToInt32(bindings);
if (port_no == random_port_no)
{
regenerate_port_no = true;
break;
}
}
}
found_valid_port_no = !regenerate_port_no;
} while (!found_valid_port_no);
int newportId = random_port_no;

I have gone though all answer here and also tested. Here is the most clean smarter version of answer for this question. However this still cant work on IIS 6.0. so IIS 8.0 or above is required.
string domainName = "";
string appPoolName = "";
string webFiles = "C:\\Users\\John\\Desktop\\New Folder";
if (IsWebsiteExists(domainName) == false)
{
ServerManager iisManager = new ServerManager();
iisManager.Sites.Add(domainName, "http", "*:8080:", webFiles);
iisManager.ApplicationDefaults.ApplicationPoolName = appPoolName;
iisManager.CommitChanges();
}
else
{
Console.WriteLine("Name Exists already");
}
public static bool IsWebsiteExists(string strWebsitename)
{
ServerManager serverMgr = new ServerManager();
Boolean flagset = false;
SiteCollection sitecollection = serverMgr.Sites;
flagset = sitecollection.Any(x => x.Name == strWebsitename);
return flagset;
}

This simplified method will create a site with default binding settings, and also create the application pool if needed:
public void addIISApplication(string siteName, string physicalPath, int port, string appPoolName)
{
using (var serverMgr = new ServerManager())
{
var sitecollection = serverMgr.Sites;
if (!sitecollection.Any(x => x.Name.ToLower() == siteName.ToLower()))
{
var appPools = serverMgr.ApplicationPools;
if (!appPools.Any(x => x.Name.ToLower() == appPoolName.ToLower()))
{
serverMgr.ApplicationPools.Add(appPoolName);
}
var mySite = serverMgr.Sites.Add(siteName, physicalPath, port);
mySite.ApplicationDefaults.ApplicationPoolName = appPoolName;
serverMgr.CommitChanges();
}
}
}

In properties of site select "Web Site" tab and specify TCP Port.
In studio to debug purpose specify http://localhost:<port>/<site> at tab Web for "Use Local IIS Web Server"
