I am authenticating my ASP.Net application through Active Directory(Microsoft ADFS Proxy). Now I want to move this authentication to WCF service so that authentication will b done there and later on this service will b flexible. Let me know how to proceed for this and what are the binding types required for this

View 3 Repliesi have an webservcie that is on my localhost(windows xp).this webservice is authenticating the user from active directory when i am testing from my system it is working fine but when i tried from other system of same domain,i am getting the users identity in webservice ,but it is giving the error while directory searching.The Authentication mechanism is unknown.The code in my webservice is
DirectoryEntry de =
new
DirectoryEntry(domain, admusername, admpassword,

1) Anonymous user disabled:
2)Integrated WindowsAuthenticated checked

I have a web application (intranet based) which uses Windows Authentication. Unfortunately there are public computers that have public logins at some company locations. My web app doesn't support these public logins because I need to know the user workingSo, even though these public users are windows authentication users, my app will fail because I have no user account setup for that particular account. I want to then try Active Directory Authentication.In my Default.aspx.cs I'd have something like this
protected void Page_Load(object sender, EventArgs e)
{try
userContext = new UserContext(); // If the authenticated user isn't a user in my system then throw an exception
}
[code]...
I am using System.directory services namespace in framework 2 to query active directory. I have used fixed user account impersonisation in the web.config file, find the code:
<identity impersonate="true" userName="enterprise ang09" password="Telcome123"/>
<authentication mode="Windows"/>
I have disabled anonymous access in IIS. Also i have given Read & write access to the account tang09 for the website virtual directory and Microsoft.NET folder located in windows folder. But still i get prompted for the domain username and password to access the website.
I have my config setup like below:
<configuration>
<connectionStrings>
<add name="ADConnectionString" connectionString="LDAP://myldap/CN=Users,DC=nevco,DC=local"/>
</connectionStrings>
<system.web>
<authentication mode="Forms">
<forms name=".ADAuthCookie" timeout="10" loginUrl="Login.aspx" defaultUrl="Default.aspx" />
</authentication>
<membership defaultProvider="DomainLoginMembershipProvider">
<providers>
<clear/>
<add name="DomainLoginMembershipProvider"
type="System.Web.Security.ActiveDirectoryMembershipProvider, System.Web, Version=2.0.0.0,Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
connectionStringName="ADConnectionString" attributeMapUsername="sAMAccountName" />
</providers>
</membership>
</system.web>
</configuration>
I can attempt to log on but every time it says I am using the incorrect username/password. Does it look like I am doing anything wrong above? Is there any way for me to find more information on why it's not finding my username/pass?
UPDATE:
Do I need to provide a Username and Password in my membership/providers section?
In the past I've developed web apps using Windows authentication however I'm now tasked with building a web app which needs to directly authenticate with Active Directory however I'm unsure about the security of doing this and have several questions.
As it stands I'm simply authenticating users by padding the username and password entered into a method which performs a search on active directory for the user's sAmAccountName, this is done within a try catch block. If the search can't run and throws an exception then the user isn't authenticated and if a result is found then the user is authenticated.
My first question is , how secure is doing this?
Secondly I need a way of storing possibly a session variable to ensure the user, once logged in, can access all the pages they have access to.
I was thinking of pulling the user's GUID out of AD and using that as the session variable.
Lastly I need to prevent people from trying to brute force my web application and to do that I've simply create a new session variable and once the count reaches 3 , they will not be able to make anymore attempts until the session variable has expired or they clear their cookies.
I think this is a more method of preventing numerous consecutive login attempts and wonder whether there's a better way? I'm considering using a captcha.

View 1 RepliesI got a request from a specific client to rather use Active Directory than SQL Server Authentication, and was wondering if someone can give me a push in the right direction.I hoping to stick to using service contracts (interfaces) and just have a different implementation (injected with castle perhaps) for each client (though it will only be one client for now using Active Directory, instead of my usual aspnet membership / role providers), but as I never did this I'm unsure if that would be possible.

It handles its own authentication.I am wondering if it is possible to modify the existing application to utilize our Active Directory users and permissions.

I am just getting started with MVC and I was wondering if someone could point me in the right direction for help with forms authentication using active directory? I have the sample site up but the results I have found on google have not been very helpful in answering this question.

View 2 RepliesI 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://domain.com 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: http://msdn.microsoft.com/en-us/library/ms180890(v=vs.80).aspx.

I want to create a small intranet web site with a login page that will authenticate against groiups of users in Active Directory. So for example if someone in Group A logs in they can get to web page X and if someone from Group B logs on they can get to web page Y. Is it possible to do this with the login controls without writing code? I thought it would be a fairly standard thing to do.

I am trying to build a web app for an intranet site that for security reasons needs to make the user type in their Windows or Active Directory username pwd manually. I have previously worked with Integrated Windows Auth but in this case, we do want them to use type in their AD credentials.
I have been trying to look up how to do this and frankly I am a bit lost. It should be a fairly straightforward task and am hoping you can point me in the right direction, with some tutorials or examples. We will be using SSL so, dont have to worry about passing pwd in cleartext over the wire.

View 1 RepliesI currently have a web application deployed on our intranet and it uses Active Directory to authenticate the user.It all works fine. But now im asked to somehow grant access to the application for outside vendors that are not part of AD, but they still need to keep the functionality of the AD as they dont want to manage all the users that currently use the application.Is this possible in some way?Currently users dont need to enter a password or username as they are part of AD, but users who are not get the " You are not authorized to view this page..."message. Is there any way to avoid that message and allow them to login using their own password?
