We have an MVC application which uses ADFS as its authentication method. All is working as should.
We are now beginning to add in 'areas' into the application to separate certain parts out.
One of these areas needs to allow complete anonymous access.
Is there a way to disable ADFS for a particular area within an MVC application?
We have tried overriding the webconfig within the area, however, no such luck.
Have you tried using the [AllowAnonymous] attribute on controller methods in that area?

I am using MVC 4 and am using Forms authentication. I have heard that MVC has it's own implementation of authentication and authorization but am not sure what it is and how to use it. What is MVC's implementation called and is it easy to migrate from forms to use it instead?
The answer is. Sort of.
MVC (versions 1-3) used standard Membership databsaes and Forms Authentication. MVC 4 uses standard Forms Authentication as well, but uses a system called WebSecurity to access it's membership system. WebSecurity was created for the WebMatrix project and MVC 4 has adopted it's use in the default templates.
You can still use the standard Membership system if you want, however WebSecurity (and in particular SimpleMembership) allows greater customization of the data.
MVC also can be configured in several ways for authorization. You can use the older web.config method, or you can use AuthorizationFilters such as the [Authorize] attribute. This still uses FormsAuthentication, however under the covers, it's just a way to configure the use of it.
What are some of the common methods to do simple user validation (account login)?
Also, can you have different authentication schemes per area?
Edit
I am creating an eCommerce site that will need to have protected actions per user. So how would one go about doing this? It will need to be able to let only authenticated users access their information.
You have several options when it comes to doing authentication in MVC:
The built-it MVC Forms Authentication (Tutorial available here and here)
Using Forms Authentication with Cookies in MVC3 (Link here)
Using Windows Authentication (Learn more here...)
Mixed Mode Authentication (Using Windows / Forms Authentication together.)
The built in Forms Authentication can allow you to limit access to different areas of your application based on Role, User among other things and it is quite easy to implement using the [Authorize] attribute.
The following would require the user be logged in:
[Authorize]
public ActionResult YourActionNameGoesHere()
{
}
Likewise, the following would require the user be logged in AND be an Administrator:
[Authorize(Roles="Administrator")]
public ActionResult YourActionNameGoesHere()
{
}
Those were just a few methods of accomplishing it, as you can see there are MANY different methods of accomplishing this - I hope this might have shed a bit of light in helping you decide.
According to the security expert on the MVC team
The only supported way of securing your MVC application is to have a
base class with an [Authorize] attribute, and then to have each
controller type subclass that base type. Any other way will open a
security hole.

please go to your model folder when you create a internet application with VS 2010. you will see a cs file there. that file holds a sample structure for User Authentication
Remember that : ASP.NET MVC is not a separate framework. it sits on top of ASP.NET so you can use System.Web.Security.Membership class on MVC as well.
Also, check your Account folder inside your view folder. you will some view samples there.
hope this helps.
My ASP.NET MVC site requires forms-based authentication for some resources (downloads, discussion forum, etc). This works great with the [Authorize] attribute.
However, I need my admin site (`~/Areas/Admin/*) to authenticate against active directory.
With regular ASP.NET or classic ASP, I would just go into the IIS config and change the directory security to deny anonymous users. However, I can't figure out a way to do that with an area.
I know putting the [authorize] attribute on the controllers in my admin area would require a login, but it'll use the same forms-based authorization as the public areas of the site. Right now that authenticates users against a database (not using the ASP.NET Membership system as it's overkill for my app). I need users to authenticate against the domain, but ONLY in the Admin area.
Ideas?
You will need to write your own custom Domain authorize attribute and add this to the admin controllers.
Have a look at the answer here: asp.net mvc Adding to the AUTHORIZE attribute
i have an asp.net mvc application that has authentication set to none in the web.config but would like to secure one view with windows authentication. is there any easy/good way to do this without changing the authentication configuration?
Think you'll need to use the Authorize Attribute.
Any reason you can't set Authentication mode to Windows for the project?
Can you write your own authorize attribute which when applied to your method checks a few things, routes you to a challenge page or performs some other action that will satisfy your credentials?
Unsure what you'll use to authorise the user. Maybe check IP, Active Directory user name etc.
If you do it like this then you can re-use the attribute on other pages which would be nice.
I'm building a .Net MVC app, where I'm using one particular view to generate an internal report. I don't want the users of the site to gain access to this page at all.
I've a console app that fires every so often which will scrape some of the details from this page by hitting it's URL.
I don't like the idea of having the URL hanging out there but I'm not sure of another way to go about it.
Thoughts on what might be the best practice way for tackling this?
Edit:
Here's what I ended up doing, created a new WCF Service project in the solution. I also copied basically what was the MVC view page into a new standard web forms page in this project. On top of adding security via the regular .net Authentication methods (eg set only valid windows users can access the page), I can also lock down the vhost to only be accessed by certain IP's.
The best practice would be to expose a wcf service for this, and set up a security model that is different than website.
If you must use MVC the best approach use forms authentication with mvc and set
[Authorize(Roles = "SecureUser")]
On the View.
If the view never needs to be rendered at all except to provide data for the console app, then why not have the console app simply connect to your database to get the data directly instead of going through the web app? You could still do this for the console app even if the view does need to be available for some users, then control access to the view using the Authorization attribute, which could suitably restricted now that an external app need not have access to it.
