PingFederate allows an SP to use either account linking or account mapping to associate remote users with local accounts for SSO between business partners (see Identity mapping). On the Identity Mapping screen, you choose which method to use in this IdP connection. You and your partner should decide in advance which option to use (see Federation planning checklist).
If you have previously set up a configuration to use an attribute contract and want to change the configuration to use account linking without additional attributes, then the existing attribute contract will be discarded.
Account linking can be used with either a clear, standard name identifier or an opaque pseudonym.
