Redirect Users To Logon Page Only If Not Authenticated In MVC?

Aug 1, 2010

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?

Security :: Grant Access To Default Page For All Users - Authenticated & Non-Authenticated?

Aug 18, 2010

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?)

Security :: Logon To Page With Already Authenticated Computer And Forms?

May 11, 2010

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.

How To Redirect Users To A Page When Not Authorized

Jan 29, 2011

I need my users are redirected to AuthError.aspx page ("You don't have the access to this page") in the case when they are authenticated but try to access the page that they cannot access (because of the role for exam). If I set up web.config so:

<authentication mode="Forms">
<forms loginUrl="~/Account/Login.aspx" timeout="2880" />
</authentication>

this is the system's wrong behaviour because an user is already authenticated and there is no need to redirect him or her to this page. But if I write here AuthError.aspx instead Login.aspx how could I redirect not-yet-authenticated user to the login page?

Security :: Redirect If Not Authenticated?

Jan 7, 2010

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.

Javascript - Redirect Users To Default Page

Dec 2, 2010

I have an ASP.NET 3.5 intranet website which has a default page with a menu and when the user clicks on a menu item, I display the page for that menu item in an iframe embedded within the default page. but if the user types the URL of a page directly in the browser, then I would like to redirect him to the default page, because all the content pages do not have a menu. (Master Pages will solve this issue, but I can't use Master page here for a reason and don't want to go into those details). how to find out if user has arrived at the page directly by typing the URL or by clicking on the menu item, so that I can decide whether to redirect or not? Is this possible to find out? btw this is an intranet site and no login is required.

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.

Security :: Redirect Authorized Users To Needed Page?

Dec 9, 2010

I have written a web application. All users open The default.aspx initially.

If user goes to auth/Login.aspx page and authorizes, he is redirected to auth/data.aspx

The problem is -

If user closes page and opens again, he is authorized (using cookies) but sees Default.aspx.

But because he is authorized already, is it possible that he is redirected to auth/data.aspx ?

OR

Is is possible to change the link in Master.Page to another for authorized users?

Security :: Changing Content For Authenticated Users?

Mar 3, 2011

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.

C# - How To Show Videos On A Second Server To Authenticated Users

Oct 18, 2010

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.

WCF / ASMX :: Enabling JSONP For Authenticated Users?

Mar 6, 2011

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.

Grant Access To Controllers / Views For Non-authenticated Users?

Feb 3, 2011

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.

Security :: Restrict Folder Contents To Authenticated Users?

Mar 26, 2011

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?

How To Auto Redirect A Forms Authenticated User To An NT Site If They Have Equivalent Credentials On The Domain

Dec 9, 2010

I have a requirement that whenever a user logs onto a website using forms based authentication [FBA] that the site checks whether they have a related domain NT user record. There will be a matching lookup table between the ASPNETDB membership database and related domain accounts for users.Whenever an FBA user logs in and a related domain account is located then the member should be redirected to an alternative site / URL which is Windows NT authenticated rather than FBA. Before transferring them I would like to be able to pre authenticate them on the windows domain rather than an additional NT Login dialog box coming up and asking them to enter the related NT credentials.Is it possible to programatically preauthenticate using NT credentials before redirecting a user to an NT authenticated site?Note: This isn't technically a single sign on style scenario. The FBA / NT authenticated sites are not related other than the relationship between the original FBA credentials and the NT credentials lookup.

Configuration :: Web Page Won't Go The Start Page After Logon

Mar 17, 2010

I have a project which uses VS 2005 and .NET framework 2.0. I saved my project and did not change any codes. Before this Monday, my project worked as normal, after I enter user name and password on log on page, it would go to start page. (The log on page is called from another project that is located on my local machine.) Cause firewall issues happend on the Monday, I reinstalled .NET framework 2.0 to get debugging worked.

Now, my project can run like usual, but after I log on, the web page will direct to start page and redirect to log on page dymatically. I am sure the codes behind start page will never redirect browser to log on page and I didn't not change any codes. The redirect code in Global.aspx is : Response.Redirect [URL]

Redirecting To Page If User Is Not Authenticated?

Mar 3, 2010

I have created a website which has Secure folder in which i have got a form which only "admin role" users can see. Now that form will appear if login is successful and it works great, if password or username is wrong then again the loginForm will appear which works great too.

Now the problem is if the users which are not in "admin role" enter the user name and password correctly, instead of coming back to the login page and showing them the "Not Authenticated" message, it gives me an error that myWebsite/login.aspx is not found. I think this is because the name for my login page is "AdminLoginPage.aspx" and which is not found and hence it shows me the error. I dont know where to change the login Page name to "AdminLoginPage.aspx"
