Security :: LDAP The Authentication Mechanism Is Unknown?

Mar 4, 2010

I am working on Web application which get the authentication details from the Active direcoty using LDAP

when I am using the function DirectorySearcher.FindOne() it gives this error message (The authentication mechanism is unknown), and I relized that I should put this line in the web.config file ( <identity impersonate="false"/> ), then this problem will be solved.

but at the same time I should put true value to the same attribute to get the correct result when I am calling this function


otherwise the returened value will be (NT AUTHORITYNETWORK SERVICE) not the authenticated user name.

Security :: Running Application Under The Security Context Of The Logged In User (LDAP Authentication)

Mar 17, 2011

We are using membership provider for LDAP authentication. It is working as it should.

But what all configuration settings I have to do so that
all the future requests to this application run under the security context of the Logged in user account not through the some default user set in IIS.

We need to have this working because all the permissions on the database are based on the logged in user.

We are using form authentication for LDAP authentication. And having impersonation = true in web.config.

Mar 16, 2010

I tried to use Authentication form with LDAP but when I run my web application I received error: Invalid dn syntax specified. This is my code:

public bool IsAuthenticated(string domain, string username, string password)
// string domainAndUsername = domain + @"" + username;
string domainAndUsername = "http://localhost:389
// DirectoryEntry entry = new DirectoryEntry(_path, domainAndUsername, password);// _path = LDAP://localhost:389/dc=example,dc=com
DirectoryEntry entry = new DirectoryEntry("LDAP://localhost:389",domainAndUsername,"rJsmitH");
Object obj = entry.NativeObject;
DirectorySearcher search = new DirectorySearcher(entry);
search.Filter = "(SAMAccountName=" + username + ")";

SearchResult result = search.FindOne();

if(null == result)
return false;
_path = result.Path;
_filterAttribute = (String)result.Properties["cn"][0];
catch (System.Exception ex)
throw new Exception("Error authenticating user. " + ex.Message);
return true;

I got exception at line Object obj = entry.NativeObject; and error message is: Invalid dn syntax specified. how can i take a right dn syntax? I tried some domain name such as: LDAP://localhost:389, [URL], ... but I still get this error

Difference Between Client Browser's Submit Mechanism And Postback Mechanism?

Sep 17, 2010

While going through MSDN I found that in button properties useSubmitBeheviour there is written that if useSubmitBeheviour is true then it cause the Button control to use the browser's submit mechanism and false then the ASP.NET page framework adds client-side script to the page to post the form to the server.

C# - Set Up Silent Authentication Using LDAP / AD

Apr 15, 2010

We're using a CMS product called Immediacy, which claims it can handle silent authentication using LDAP / AD but just can't get the thing to work.

point me to a good article or post that lays out the steps to do the above (assuming it's achievable)?

Basically, we need to secure pages on our intranet, and, as our firm is full of 'very important people' who 'don't have time to log in' this is an almost essential requirement.

LDAP Authentication From .NET Using Proxy User?

Feb 3, 2010

We want to use a "proxy user" to connect to an LDAP server (Active Directory, Novell, or otherwise) and then make sure that the user trying to log into the application has typed in an acceptable user name and password. I have got the code for connecting to LDAP just fine, but I'm at a loss as to how to check the user name and password. Can you do this through an LDAP query?

Here's the guts of my code so far:

Public Function Authenticate(ByVal UserName As String, ByVal Password As String)
Dim LDAPServer As String = ConfigurationManager.AppSettings("LDAPServer")
Dim proxyUsername As String = ConfigurationManager.AppSettings("LDAPProxyUser")
Dim proxyPassword As String = ConfigurationManager.AppSettings("LDAPProxyPassword")
Dim entry As DirectoryEntry
entry = New DirectoryEntry(LDAPServer, proxyUsername, proxyPassword)
'This performs the LDAP authentication'
Dim obj As Object = entry.NativeObject
Dim search As New DirectorySearcher(entry)
search.Filter = String.Format("(SAMAccountName={0})", UserName)

'How do I check the password now?'

Dim result As SearchResult = search.FindOne()

If result Is Nothing Then Throw New Exception("Unable to find SAMAccountName")

C# - Forms Authentication Against Active Directory - LDAP Protocol

Jan 27, 2011

I need to create a web page that authenticates users against an existing active directory. The domain is actually a cloud computing configuration where there is a domain controller and multiple other servers on the stack.

I understand that objects from the System.DirectoryServices namespace can be used. However, I cant seem to path the code to the active directory through the LDAP:// address. There doesnt seem to be any communication going on. I suspect there is some initial configuration necessary or security measures blocking the communication.

I am working with this example from MSDN:

I get an error that says the server is not operational.

Active Directory/LDAP :: AD Authentication Using Forms - Dealing With Roles

Mar 2, 2010

I am not really sure if this post should go in the Security section or the Active Directory / LDAP section....with that being said I am looking for advice on how to best accomplish my goal(s), I am working with FORMS authentication, using active directory (across 2 domains). I have got authenticating working correctly based upon the article at: [URL] now - my questions:

1. What is the best way to deal with roles? What I would like to do is restrict access to my application so that only the users that are authorized to use the application can login - not everyone in the AD. My gut feeling tells me I would use an AD group for this. Furthermore, a subset of these users in this group will be allowed to access the data maintenance forms

2. Ideally, in a perfect world, I would like to write this authentication piece as a separate project - this way it could be used for multiple projects - the only thing different would be the AD groups it would be checking. Is there a way that I could set which AD groups or roles in each projects web.config?

Am I approaching this the correct way? What is typically done?

Security :: System.IO.IOException Unknown User Name Or Bad Password?

Feb 15, 2011

I cannot for the life of me figure out why I cannot wrtite a file to a directory inside of the website. I have this working on a Windows 2003 Server using IIS6. I've ported this web app to a 64bit Windows 2008 server and I am unable to have my web app write a file to a directory. I have shared and given security access to everything under the sun on this server to that particular folder and still no luck. My dev workstation with Visual Studio 2010 has no probelm saving a file to that directory. So it has to be something with the web server account. I am using Windows Authentication. I have an account in our Active Directory that is being used.
