FreeRADIUS does not officially expose Peer-Id or Server-Id. But the certificate subjectAltNames are available via the policy engine. The greater difficulty is *which* Id to use. RFC 5216 Section 5.2 says: It is possible for more than one subjectAltName field to be present in a peer or server certificate in addition to an empty or non-empty subject distinguished name. EAP-TLS implementations supporting export of the Peer-Id and Server-Id SHOULD export all the subjectAltName fields within Peer-Ids or Server-Ids, and SHOULD also export a non-empty subject distinguished name field within the Peer- Ids or Server-Ids. All of the exported Peer-Ids and Server-Ids are considered valid. > and it may be difficult to implement in practice due to ordering.

We expose the certs to the policy engine, along with various fields. Having the TLS exporter use more data should just be about updating some code.
