Security :: Implement A Web App Whose Users Must Be Authenticated?
Feb 12, 2010
I'm setting up a new web forms app and want to use ASP.NET membership. All my users must be authenticated. What is the best way to implement this?I'd love to deny all unauthenticated users in the root folder of the app by setting this in web.config but then where would I put the login folder? I'd like the login folder to be a subfolder of my root folder so that the URL can be www.myapp.com/login/Another idea is not to put the restriction in the web.config but put the logic in Session_Start in global.asax but I really like the idea of controlling who can see what using web.config files.

I've a default.aspx page in my application's root folder. I added a a page in the root of inetpub that redirects requests to the default page. The idea is that the user need only enter the server name to get to the default page. How can I set things up so that all users have access to the default.aspx and that they only have access to the other pages once they've been authenticated?
I am using Windows Integrated Security and the users are being challenged and authenticated properly. I want them to be able to access Default.aspx without any challenges.
(On a side note which may answer this question, when using WIS does the user *allows* have to be challenged? Isn't it possible to pass through their Windows User and ID without the prompt?)

we want to have a fronend to a custom databasince, since I do have experiance with HTML/CSS and have used VB.NET before, I'm the one that gets to make it.
problem is, the one thing I have not used before is the autentication system in ASP.NET, I want to use single-signon for the system.
and I do have this right now, the only problem I have is how do I check if a user is logged in, and change the page content for autenticated users.
the template does have this:
[Code]....
which does indeed change the login view, problem is, how do I change this to change the pages and menu.this:
[Code]....
has to be a longer menu that also gives options to insert data into the database and/or remove/update the data.

I am using the membership provider and am reasonably comfortable that all of my web pages are safe.Some of the pages contain hyperlinks to documents (pdf, xls, etc.) stored in a folder under the root of the web site. I have disabled the ability of users to anonymously list folder contents, but I don't see a way to keep anonymous users from accessing the documents if they know the specific URL for that document. Example; if the document contains a spreadsheet of current sales, I don't want an ex-employee (who captured the URL while working here) to be able to bring up the current document.asswording the documents isn't a good choice because there are hundreds and we'd like to avoid changing them all every time someone leaves, or weekly, or whenever...Is there a way to restrict access to all contents of a web folder to people who have been authenticated?

I am not able to allow/deny users based on roles in the web.config (using <location path>). The following does not work even if the user is in the 'Admin' role:[Code]....
I am able successfully execute IsUserInRole() and GetRolesForUser() in the codebehind and get expected results. The same applies to the web.sitemap, adding roles in there do not seem to apply to the user even if he is a member of the role.
Here is my web.config (trimmed some sections out so it's not too long):[Code]....
And web.sitemap:

I have a simple user-registration website where I keep records of registered users. I also have an admin page to upload videos, however videos are uploaded to a different server.
I'm using the <video> tag to show the video:
<video width="560" height="340" controls>
<source src="path/to/myvideo.mp4" type="video/mp4";>
</video>`
I want to show this video only to my registered users on my website, since the video is on second server, how can I protect it?
I thought I could build an application and install it on second server, this app will watch whether the requested url is for videos, if so then it'll redirect the user to my login page and here he'll be authenticated and again redirected to the same video url.

In my ASP.NET MVC project i have following tag in in web.config file
<authentication mode="Forms">
<forms loginUrl="~/Account/LogOn" timeout="2880"/>
</authentication>
This causes even the authenticated users but unauthorized resource requested users to redirect to logon page. but i need only to redirect this page if user try to access unauthorized page and not already authenticated(logged on) and redirect to custom page.
Is there easy way to do this without writing custom action filter?

We have a series of Silverlight apps that use WCF services via SOAP for just about everything. As we migrate to AJAX we've been hoping to expose the same services via JSONP with little more than config changes on the server.Although the message "Cross domain javascript callback is not supported in authenticated services" seems pretty explicit, I'm hoping there might be a way to allow it. We have a need to expose user-centric data across domains, but we'll need to roll our own JSONP to make it happen if this is a hard "unsupported". It would be even better if there was a way for the server to validate the referrer against the client access policy we provide for Silverlight clients, but for now we just need the general requests to not fail if the user happens to have an auth cookie for our domain from a previous visit.f there's no way to allow this to just work, we're also considering the option of channeling the requests through an IFRAME, but we're definitely open to other recommendations.

I have an MVC 3 application which uses asp.net authentication. I have just created a custom errors controller and a couple of views for unknown errors and 404's. This works fine when I am logged into the application but if an internal server error happens during logon I would like to display the error/unknown view. However I just keep getting redirected back to the login as I am not authenticated.
I have added a location path for 'Views/Error' to my Web.config to allow access to all users but I am guessing it's the controller access that is causing the redirection.
Is there any way you can allow this in MVC or do I need to think of another solution? Just did not want to add a generic message to the login page as that's what my unknown error view is for.

I have a login page. Once a user is authenticated they are redirected to another page, (called pg2). I don't want just anyone typing in the url and getting to pg2. If they are not authenticated I want them to redirect to login.aspx. To achieve this, I'm using this code below. But it's not working. I am using a nested master page and I don't know if this is causing the problem.

I got only one ideas to control with the session. When user log into the master page, I insert the current login user and session ID and active status to the SQL table. if user logout manually or close the browser or session expired, I want to change the inactive status. So I can check how many active user are there and the system can prompt the required info to the user. But now, I can't find the soultion to change the inactive
status in above condition.
That doesn't seem right to me. I m sure I 'm making incorrect assumption about this matter.

Show Authenticated user on Intranet:
Response.Write("UserName is: " + User.Identity.Name);
In Web.config:
<authentication
mode="Windows"/>
<authorization>
<allow
users="?"/>
</authorization>
This works fine on local server. But not on Intranet.
On Intranet, it was working fine on IIS 6.0.
But on IIS 7.5, the user doesn't get authenticated.

Ok so I've created a login page that accesses my Active Directory and challenges against it. What I would like, is if a user is logged onto the computer within the intranet with Active Directory Credentials for them to bypass the login to the web page.
However if they are outside of the building on a random computer, they should be presented with a login box just like they are now.

I am using the sqlmembership provider with the login control from the toolbox. I want to capture the validated username after the user is authenticated. I need the username so that when the user adds or modifies a record i can have an audit trail. where is the best place to capture the validated user right after authentication? Ideally, i would like to capture it on the login form but how?
