When you do not want to store the claims provided by the external identity provider in the CoreOne Suite Meta Directory but you would like to include the claims in the token, you can configure a simple claim mapping. I.e. you can map the external claim http://schemas.xmlsoap.org/ws/2005/05/identity/claims/givenname to the claim given_name.
Starting from version 8.0: When configuring a mapping, you can also specify if this mapping can be used to identify a user uniquely in an auto merge process by setting the can identify a user flag.
