This walkthrough demonstrates how to use the Security Application Block to authenticate a user using a token.

To reproduce the demonstration

  1. Authenticate the user. The following code demonstrates how to authenticate a user using the System.Web.Security.Membership class.
  2. Create the security cache by adding the following code.
  3. Call the SaveIdentity method on the security cache object by adding the following code.
  4. Call the GetIdentity method on the security cache object by adding the following code.

This returns the identity associated with the token. If the token has been expired, or is not valid, GetIdentity returns null (C#) or Nothing (Visual Basic).
