The choices of name-identifier types depend on whether you use the SAML or WS-Federation protocol. For more information, see one of the following.
Note:

The Identity Mapping window does not apply for connections using the WS-Federation protocol in conjunction with JSON web token (JWT)-based single sign-on (SSO) tokens. Instead, work with the SP to define an attribute contract that it can use to map users to accounts at the SP site.
