OU level authentication - AD/Ldap

Posted By:      Posted Date: September 15, 2010    Points: 0   Category :ASP.Net
I want to write a process where i need to authenticate an user against a particular OU in Active Directory. If the AD holds 50 OUs I don't want the process to look into all 50 OUs , instead it should look into a particular OU( for eg: OU=dotnet users)  to authenticate the user. This is to improve the performance by avoiding the time for looking into the entire directory. How can I achieve this? Appreciate your help!

helped needed: ASP LDAP authentication failed in IE 8


I use the following code to do the user authentication through Active Directory using LDAP.

entry = new DirectoryEntry("LDAP://" + server, user_name, password);
if (!string.IsNullOrEmpty(entry.Name))
EmployeeNetId = entry.Username.Substring(0, 3);

// Retrieve EmployeeId, and Employee Full Name
EmployeeId = -1;

It works for Chrome, Firefox with no problem. But with IE 8, it works sometimes, and failed on some computers. When it failed, I figured that I need to check SSL 2.0 in IE 8 Internet Options.  It's weird because in those computers that IE 8 works, SSL 2.0 is also unchecked.

Am I using some deprecated method? Or How do I specifiy the SSL version options in the LDAP connection?

Solved: LDAP authentication: error code 49 - 80090308, comment: AcceptSecurityContext error, data 52

Hi, I have a problem conneting to another domain (far.away.domain). We have a two-way trust to this domain. Also I can access the DS using ADSI edit and our Administrator account (ourdomain.com). I tried several types of credentials (userid = "CN=Administrator,CN=Users,DC=ourdomain,DC=com", "Administrator @ ourdomain.com" (without blanks)...). Connecting to ourdomain.com is no problem, but to far.away.domain I can't connect, I always get the error 525 (user not found). What could be the problem? Have I to use an entry from the ForeignSecurityPrincipals CN of the far.away.domain? I also tried to connect using Softerra LDAPBrowser and a command line ldapsearch without succes and with not a better error message. But why is it not possible to use a trusted account, or is this a active directory feature and does not work with pure LDAP bindings? Best regards, Nils.

A Low Level Look at ASP.NET Architecture

ASP.NET is a powerful platform for building Web applications, that provides a tremendous amount of flexibility and power for building just about any kind of Web application. Most people are familiar only with the high level frameworks like WebForms and WebServices which sit at the very top level of the ASP.NET hierarchy. In this article I'll describe the lower level aspects of ASP.NET and explain how requests move from Web Server to the ASP.NET runtime and then through the ASP.NET HTTP pipeline to process requests.

Explained: Forms Authentication in ASP.NET

This module explains how forms authentication works in ASP.NET version 2.0. It explains how IIS and ASP.NET authentication work together, and it explains the role and operation of the FormsAuthenticationModule class.

Using Forms Authentication in ASP.NET - Part 1

Classic ASP developers often had to "roll their own" authentication scheme, however, in ASP.NET much of the grunt work has been taken out. This article outlines how things have changed and how FormsAuthentication can be used to secure a Web site with a minimal amount of code.

ASP.NET Forms Authentication - Part 1

Often, in legacy Web applications, users authenticate themselves via a Web form. This Web form submits the user's credentials to business logic that determines their authorization level. Upon successful authentication, the application then submits a ticket in the form of a cookie, albeit a hard cookie or session variable. This ticket contains anything from just a valid session identification access token to customized personalization values.

ASP.NET forms authentication with roles

.A timeout is specified in minutes. This is "time since last request" not the "time since login". If a login is indicated to be persistent (described later) this is ignored.
.A protection method is specified for the cookie.
Next I wanted to specify a folder to which access is restricted to people who have logged in. To do this I entered the following code in the web.config file (beneath

Web Matrix + Windows Authentication


I'm curious if its possible to get windows auth working with asp.net webpages/webmatrix.

I've got it published to IIS with windows auth turned on and anonymous/forms/basic turned off.

I'm guessing the WebSecurity Helper probably won't work here but can you access User.Identity.Name etc?

Sorry for the newbie questions, I've only just started working with asp.net ^^,

Problems with Forms Authentication in DD 4 site


Hello,  I am seeing a strange problem with Forms Authentication in my DD site.   A user logs into and can view/edit/delete data all day, but when they execute a Custom Filter against data (for example , a control DynamicData/Filters/CustomerLastNameSearch.ascx ) then the site auth fails, and redirects to the log in screen.

in web.config I have

     <authentication mode="Forms">
            <forms name=".Star" loginUrl="~/Login.aspx" protection="All" defaultUrl="~/Default.aspx" path="/" timeout="43200" cookieless="UseCookies" />     

Offhand, I am thinking two things : that DynamicData/Filters path requires some special handling for some reason, or the control extension ascx is causing auth to get confused.   Has anyone else experienced this or have any suggestions?  Thanks!
