Claim name—The friendly name of this claim.

Claim type—A common name is an arbitrary string that is used to personalize a claim. A security token may contain only one common name claim. It is important to note that there is no mechanism to guarantee the uniqueness of the common name claim or a particular partner’s authority for asserting a given common name. Therefore, use caution when using this claim type in authorization decisions.

Identity claim types include e-mail, user principal name (UPN), and common name. If more than one of these identity claim types is present in a token, the identity claims are populated in the following order:

  1. UPN

  2. E-mail

  3. Common name

Limit auditing—Specifies whether the claim value is audited or shared when the claim is produced or mapped.
