Asp.net-mvc – ASP.NET MVC – Authenticate users against Active Directory, but require username and password to be inputted

asp.net-mvcasp.net-mvc-2asp.net-mvc-3forms-authenticationwindows-authentication

I'm developing a MVC3 application that will require a user to be authenticated against an AD. I know that there is the option in MVC3 to create an Intranet Application that automatically authenticates a user against an AD, but it uses Windows Authentication and automatically logs them on. This application may be accessed on 'Open' workstations where the user will need to enter their Domain Username and Password. Any examples or online tutorial would be great. An example project would be exceptional.

Best Solution

You can use the standard Internet application template with forms authentication and insert an ActiveDirectoryMembershipProvider into the web.config:

<connectionStrings>
    <add name="ADConnectionString" connectionString="LDAP://YOUR_AD_CONN_STRING" />
</connectionStrings>

<system.web>
    <authentication mode="Forms">
        <forms name=".ADAuthCookie" loginUrl="~/Account/LogOn"
               timeout="15" slidingExpiration="false" protection="All" />
    </authentication>
    <membership defaultProvider="MY_ADMembershipProvider">
        <providers>
            <clear />
            <add name="MY_ADMembershipProvider" 
                 type="System.Web.Security.ActiveDirectoryMembershipProvider" 
                 connectionStringName="ADConnectionString"
                 attributeMapUsername="sAMAccountName" />
        </providers>
    </membership>
</system.web>

In this way you get the Internet application template login form, and it validates against AD for you.

Then it's just a matter of some AccountController cleanup to remove reset password/change password/register functionality leaving just Login.

R – Mixing Windows and Forms Authentication in ASP.NET MVC

It seems the answer is no. We've had to set up 2 sites, the main application with forms authentication and a separate windows authenticated site which redirects to the forms site with a token which expires quickly telling the forms site that an authenticated user is incomming.

Receiving login prompt using integrated windows authentication

I have a Windows 2008 server that I'm working on, so my answer is not completely the same as what the OP has on a Windows 2003 server.

Here is what I did (recording this here so I can find it later).

I was having this same issue:

In my Web.config file, I had this section:

<system.web>
    <authentication mode="Windows" />
    <authorization>
        <allow users="*" />
        <deny users="?" />
    </authorization>
</system.web>

Under IIS, all of these seems to be solved under the Authentication icon.
