forms authentication error 401 Port Jefferson, Ohio

For example, you could use Forms authentication when authenticating a user for a Web page, but Basic (or Digest) authentication when authenticating for a private RSS feed. Since ASP.NET Forms authentication uses, by default, a login page with the name Login.aspx, and tacks on a ReturnUrl querystring parameter, the first discriminator is designed to evaluate to True when Figure 5 illustrates how the Forms authentication workflow is suspended by FormsAuthenticationDispositionModule, and how BasicAuthenticationModule adds the necessary headers to the outgoing response after FormsAuthenticationDispositionModule has done its job. The actual contents of the challenge and response are specific to each scheme, and they are detailed in RFC 2617 for Basic and Digest.

On 6.1 and later, select the root of the web app (or site), click on "basic settings" on the action pane and click "Test settings" –Stephane Feb 12 '13 at 14:56

Determining When to Switch Authentication Schemes The sole responsibility of FormsAuthenticationDispositionModule is to ascertain when to mute Forms authentication and set the response status back to unauthorized (401).

One side effect of this fact, which is discussed in more detail in the "Installing and Configuring MADAM" section, is that MADAM's supplied Basic challenge will be ignored by a user This is not something you can easily override, so your only recourse would be to do something like checking in your Login page to see if they are already logged in, Access is denied.

Does an index have a currency? I got it working by trying either of your suggestions. In ASP.NET 2.0, however, the Login Web control automatically executes the necessary FormsAuthentication methods. This will bring up the Authentication Methods dialog box (see Figure 9), which lists those authentication methods that are supported.

With Basic and Digest authentication, however, there is no separate Web page to create, where the credentials need to be collected or validated. User entering incorrect, and then correct credentials As you can see in Figure 6, the FormsAuthenticationDispositionModule is not involved in authentication of the client's credentials; its sole task is to mute the One characteristic Basic and Digest share is that the WWW-Authenticate header specifies a realm.

Thread Status: Not open for further replies. 0005785 Hi, I have configured my site to use Forms Authentication but it doesn't redirect me to the Login page. To overcome these limitations, an HTTP Module can be created to replace the Forms authentication workflow with the standard HTTP authentication workflow when certain conditions are met. This 302 status is what causes the user agent to redirect to the login page.

Is intelligence the "natural" product of evolution? Instead, use the answer suggested here, but instead of using Ajax, add some logic to determine if the redirect (302) is to the login page and the request is already authenticated Thank you! –Randy Sep 28 at 19:31 | show 1 more comment up vote 16 down vote If you're using IIS 7 do something like this: Select your site. Furthermore, implementing Forms authentication has become substantially easier with ASP.NET 2.0's Membership capabilities.

If IIS is set up to support authentication schemes, it detects the 401 status being sent back to the client, and tacks on WWW-Authenticate headers for each scheme it supports. In this scenario, the Forms and Basic (or Digest) authentication schemes would both authenticate against the same credential store, most likely a database. asp.net asp share|improve this question asked Feb 12 '13 at 12:47 Zim3r 69151536 1 Have you enabled anonymous authentication on the web application ?

You don't need a seperate web.config, you can use the location setting in your main web.config. For example, Greg Reinacker published a simple implementation of HTTP Digest authentication that consists of a single class named DigestAuthenticationModule.
