As mentioned in the previous section, a web application can have multiple authentication providers. Additionally, authentication providers can get their user databases from a number of different places, including from Active Directory, a SQL database, or another federated environment.
In this example, we're going to create a new web application (although this process can also be used for an existing web application) and connect it to both an internal authentication provider (NTLM) an external identity provider that's been configured (the ASP.NET IIS authentication database).
To configure a web app to use multiple providers, follow these steps:
- Launch Central Administration and navigate to Application Management | Manage Web Applications.
- From the Contribute group on the ribbon, select New.
- In this example, create a new IIS website for the web application. Specify a site name, port, and path. Leave anonymous access off...
