I have seen other threads that kind of tell you how to do this but those had the authentication boxes inside the actually the page on the web site I want to access it is in a pop up box so I can't see the source code for it.

View 1 RepliesI am trying to restrict access to an intranet site via Windows authentication. I would like to control access via active directory user groups, but my added AD groups don't appear to be recognised by .net. I started with the following test code in my app to determine if the group could be used...
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Me.Label1.Text = User.Identity.Name
[Code]...
The isuserinrole returns false and the group is not shown in getrolesforuser. However, getrolesforuser returns all of the built in windows groups as well as custom admin user groups created by our anti virus software (SOPHOS). This tells me that .net doesn't seem to have any issue with reading our active directory but I don't understand why my custom group is not being recognised.

View 4 RepliesThis program is going to submit GET data to our webpage. However, we don't want users accessing the webpage any other way than the program. We can prevent users from sharing the program using HWID authentication, but nothing prevents them from using a packet scanner to get the URL of the webpage. We thought about user-agent authentication, which we will implement, but user-agents can easily be spoofed.
how can we prevent users from accessing the webpage directly, instead of through the program?
Currently we will be implementing:
HWID Authentication to use the program User-Agent Authentication to access the web page Instant IP Blacklisting to anyone accessing the webpage without the proper User-Agent

View 1 RepliesI have a vb.net web application running on a local server with IIS6 installed. I was using Integrated Windows authentication for allowing uses to access the data in the application which is a combination of flat files on a local directory and db information. That worked great until another dataset was brought online and incorperated into the existing application. The problem is the flatfiles for the second dataset are stored on another server. So, although user could see the file files in the application window, if they attempted to open one it would say access denied on the directory.
I explained this to our network administrator who explained the users didn't have access to that server (even though both servers had the same permissions) and that the application wouldn't work. The only way in which I got it to work was I had to
Enable Anonymous access and use a windows user account for that access, which works. However, the application requires the users NT account for various reasons. How can I get this to work with Integrated Windows Authentication?

View 5 Replieshow to use Windows Authentication in a WPF app. I wouldn't have thought that it would be any different than in any non-WPF app, but it seems that it is. I want to go into my project Properties -> Application and ensure that Windows Authentication is on, but that option is not available in a WPF app (as the following document confirms).

If I ignore all that and just look at My.User.Name (VB), it is empty. This tells me that somehow Windows Authentication is not enabled.My plan is to use a PrincipalPermission attribute to restrict access to certain parts of my app (or perhaps the entire app, by applying it to Application_Startup()).

View 1 RepliesI have a application that prints labels on a community computer.I would like to add a Windows authentication login form to allow any of our employees to access a configuration screen.The request would bring up the login form if the login passed (meaning the username / password was correct) the configuration form would open.Otherwise the user would just get a warning Msgbox.So far all of the examples I could find either apply ASP.NET or use the logged-in user. Not for additional access as I'm trying to do.
View 7 RepliesI'm writing an internal web application right now (with ASP.Net Web Forms), and it presents an odd problem. I have to be able to impersonate the currently logged in windows user, and execute a command based on their Windows Authentication to log in.. AND ... if they don't have Windows Authentication set up in the application I have to use to log them in, I have to be able to accept a user name and password. I also have to write the application in .Net 4.0, and secure it as much as possible. I got this to work by NOT utilizing Windows Authentication or Forms Authentication in the web.config, and instead setting session variables to guard against user accessing pages in the web app other that the log in. I did this by creating an oddly name session variable with a value based on their user name (windows auth or not), and then a secret session variable. The secret variable is in the web.config as a 256bit encrypted string, in which I decrypt, and set as the session secret. In order for the page to load, the first session variable can't be blank, and the second variable has to equal the decrypted key value... if the variables don't pass inspection, it redirects them to the login page. I set this up on every page, generic handler, and webservice method in the web app. I make the session timeout after a few minutes of no activity, and on log out, I set all session variables to nothing, and expire all cookies. (I also disable all cache).
My question is... Does this offer comparable security to that of Forms authentication? I have always used Forms authentication, but can't use it here. If I did, the users would have to reconfigure settings in IIS and in he web.config to toggle login procedures (From my knowledge, you can't use both Forms authentication, and windows authentication to manage the security of your pages and other web resources). With the method described above, I can accomplish the best of both worlds, but am curious about the security of my methods. Is there anything else I can implement here to assure the utmost security other that using forms authentication? Is it possible to accomplish the same level of security of Forms authentication without using it?
I am working on a windows application and I am developing application using VB.Net.
