Transforming an Incoming Claim
Applies To: Active Directory Federation Services (AD FS) 2.0, Windows Server 2012
Using the Transform an Incoming Claim rule template, you can select an incoming claim and map it to a different claim type. You can also map its claim value to a new claim value. You can send multiple claim values with the same claim type using this rule.
For example, you can use this rule template to create a rule that will send a group claim with a claim value of Purchasers when there is an incoming group claim with a value of Admins.
In the acceptance transform rules of a claims provider trust, this rule template is useful for transforming incoming claims from the claims provider into trustworthy equivalents. Claim types or claim values can have a different meaning in your organization than in the claims provider organizations. You can use this rule template to normalize the claim types and values that come from the claims provider. In the issuance transform rules of a relying party trust, this rule template is useful for transforming claims for the specific relying party. Claim types or claim values might have a different meaning for a specific relying party, and this rule template makes it possible for you to change the outgoing claim types and values for a single relying party.
You can find incoming claims in the input claim set of the rules. For more information about the input claim set of the rules, see Using Claim Rules for Issuing Claims.
