This VS 2012 extension is meant to allow me to add a local Development STS to my MVC application http://visualstudiogallery.msdn.microsoft.com/e21bf653-dfe1-4d81-b3d3-795cb104066e
I follow the very simple instructions e.g. Right Click the project name and select Identity and Access in the menu. Select your Identity Provider and the OK to apply the settings to your web.config.
I run my MVC 4 application and it redirects immediately to login.aspx
I'm guessing there are special instructions for MVC 4.
What are they?
Where do I find them?
EDIT
To be clear I have created a ASP.MVC 4 Internet application in visual studio 2012. Then I am using the Identity & Access Tool to add a local development STS to Test my application.
I am running the site on a local IIS Express
When I debug the application I am redirected to
localhost:11378/login.aspx?ReturnUrl=%2f
This occurs even if I remove forms authentication as suggested in advice already given.
In my case I added this
<system.web>
...
<httpModules>
...
<remove name="FormsAuthentication" />
</httpModules>
</system.web>
and this
<system.webServer>
...
<modules>
...
<remove name="FormsAuthentication" />
</modules>
</system.webServer>
EDIT
The next problem you might get is this
A claim of type
'http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier'
or
'http://schemas.microsoft.com/accesscontrolservice/2010/07/claims/identityprovider'
was not present on the provided ClaimsIdentity. To enable anti-forgery
token support with claims-based authentication, please verify that the
configured claims provider is providing both of these claims on the
ClaimsIdentity instances it generates. If the configured claims
provider instead uses a different claim type as a unique identifier,
it can be configured by setting the static property
AntiForgeryConfig.UniqueClaimTypeIdentifier.
add these 2 claims to the Development STS in the Identity and Access Tool
http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier
http://schemas.microsoft.com/accesscontrolservice/2010/07/claims/identityprovider
and add this line to your Global.asax
AntiForgeryConfig.UniqueClaimTypeIdentifier = ClaimTypes.NameIdentifier;
This article helped me
Removing FormsAuthentication module worked for me.
<httpModules>
...
<remove name="FormsAuthentication" />
</httpModules>
I had a similar problem with my MVC4 application on local IIS Express.
It turned out that Windows Authentication was enabled for the project. Disabling Windows Authentication (in project properties pane -- press F4) fixed the problem.
