This works as follows (as shown in the diagram above):ДЎ) Anonymous request to page.aspx (a protected page in your app)ДЄ.

This way, our Windows authentication challenge will work correctly. Secondly, using a wrapper module, we will disable Forms authentication for the gateway (login) page. Luckily, this maps well into the Forms Authentication model of having a separate login page which will become our gateway. The answer lies in separating the windows authentication and forms authentication transactions into two separate pages вЂ“ one page will be the gateway page that requires Windows authentication, and the other page (or pages) will require forms authentication.

Additionally, because Forms authentication is enabled for the entire application, there is no way to enable it for a part of your app and not for another вЂ“ which presents a problem, because Forms authenticationвЂ™s 302 redirect challenge is incompatible with the 401 вЂњHere is how to do it вЂ¦ДЄfter posting the list of ASP.NET breaking changes for IIS 7.0, a number of people contacted me asking for a way to accomplish this. But, in Integrated mode, both Windows and Forms authentication run during the single stage authentication process, which makes it impossible to first authenticate with Windows authentication, and second authenticate with Forms authentication. This works on IIS 6.0 and on IIS 7.0 in Classic mode. You could do that by enabling Windows authentication and disabling Anonymous authentication in IIS, which would cause the request to be rejected by IIS before it would arrive in ASP.NET, thereby making sure that your users were first authenticated by Windows auth. For some reason, you want all users to first log in using their Windows credentials, and then log in using their Membership credentials and Forms authentication. But, all of your users also have Windows accounts on the server (or Active Directory). You have a login.aspx page which allows your users to log in using Forms authentication. Because of this, certain authentication schemes that relied on the two-stageness of the authentication process used by ASP.NET applications in the past no longer work. Unfortunately, one of the limitations of a single-stage authentication model is that it is done in a single stage (imagine that!). The problem: using ASP.NET Forms authentication and IIS Windows authentication in the same application If you regularly troubleshoot IIS errors, manage Windows Servers, or tune ASP.NET performance, definitely check out the demo at Popular example вЂ“ everyoneвЂ™s favorite Forms authentication, backed by a Membership credential store and login controls, being used to secure access to your entire Web site including your images, PHP pages, CGI applications, and so on. The client must return this cookie with each subsequent request in order for the request to be authenticated.Update: We recently launched a service that significantly helps you understand, troubleshoot, and improve IIS and ASP.NET web applications. After authenticating via the.HTML form, an authentication cookie is set by the server. SSL/TLS must be enabled for this authentication.ДЇorms-Based Authentication: Forms-based authentication (FBA) authenticates a user using an.HTML form. The server is configured to map certificates to one or more Windows user accounts. Kerberos authentication is only available for Active Directory accounts, whereas NTLM can be used for local account.Д¬lient Certificate Authentication: In Client Certificate Authentication the client presents a certificate to the server.

NTLM authentication uses a hashed version of the userвЂ™s password and Kerberos uses shared secrets between the client, Active Directory domain controller, and the IIS server to authenticate the user. The password is never sent as clear text across the network. Integrated Windows Authentication: Integrated Windows Authentication uses two separate authentication mechanisms NTLM v2 and Kerberos. Windows is unable to store MD5 hashes of passwords for local accounts, thus Digest authentication is only available for Active Directory accounts. Digest authentication hashes the userвЂ™s password using MD5 and sent across the network. IIS 7.0 uses fixed user account (USER_) to process the requestД«asic Authentication: In Basic Authentication the end-user is prompted to supply credentials, which are then transmitted unencrypted across the network.Дigest Authentication: In Digest Authentication the userвЂ™s password is not passed in clear text across the network. Anonymous Authentication: In Anonymous Authentication the end user does not supply credentials and the user can use the service anonymously.
