if you have implemented Forms Authentication with Active Directory in ASP.NET 2.0, I have implemented [URL] mentioned on this page. But I am getting an error saying "Provider must implement the class 'System.Web.Security.RoleProvider".

View 3 RepliesI 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

I am trying to set up an intranet application with Forms Authentication configured for AD. (Don't ask why, it's for the boss). Anyways, I got it configured to where everybody on the domain can log in but I need to restrict it to a security group that IT has set up for me.
The problem I am having is that users in the SG can not log in to the site. I tried just adding

without a role manager but it didn't work. Then I tried adding the role manager below (among others...).

Also, how should the user defined in connectionUsername and connectionPassword be set up? Must it be the same as the user I am running the application as?

View 7 RepliesI 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. This site is going to be an intranet page that we want users to be able to access without logging in when they access it from our network while they must login when trying to access it from home.
View 7 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 get an error that says the server is not operational.
What's the easiest way to make Forms Authentication functional? Do I need to setup IIS/Active Directory? If so, how would you code that?

I 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?

Forms authentication using Active Directory Group
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?
I've written a small ASP.NET 3.5 application to allow users to update selected account attributes on their own. Everything works fine when I use Basic Authentication, but because the dialog that is presented is less than ideal, I'd like to use forms authentication to give the users more instruction on how to log in. My problem is that in order for the user to update their account information, I have to have the application impersonate them for the update actions. I've scoured the internet trying to find a solution to my issue, but nothing fits or works. I have tried setting the web.config:
[Code]....
I also tried using the LogonUser method to create a user token and backend the authentication that way, and it doesn't work either.
[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.

Authentication With Active Directory AD Getting propertie
[Code]....
In my website i want to use active directory users for authentication. how can i do this.
View 2 RepliesI am using Visual web Developer 2010 Express.
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 restrict access to the webpage using a security group. find the code in the web.config file:
<authentication mode="Windows"/>
<roleManager enabled="true" defaultProvider="AspNetWindowsTokenRoleProvider" />
<authorization>
<allow roles="enterprisenet.orgNMR Helpdesk Supt" />
</authorization>
Code in the code behind file of the aspx file i am trying to access:
if (User.IsInRole(@"enterprisenet.orgNMR Helpdesk Supt"))
{}
else
{
Server.Transfer("noaccess.aspx");
}
Group is located in enterprisenet.org/Groups/NMR Helpdesk Supt . Its not working as expected.
