It means that session resumption works against a cluster of RADIUS servers
with a front end load balancer, without the need for a common session data

Granted, that's only strictly true for EAP-TLS and EAP-TTLS/PEAP (if
anonymous outer identities are disallowed), but it's still useful.
An option to allow it would be appreciated.

If OpenSSL presented a sane API or serialised ex_data, we could've embedded
the session-state list in the ticket, and stored the inner identity too.
That would have negated the need for a common database or store for anonymous
outer identities. Unfortunately OpenSSL doesn't do either of those things...

After commenting out SSL_OP_NO_TICKET in the wpa_supplicant I can see
sessions being resumed successfully.

I've tested the case where the client presents the session ticket extension
and support is not enabled on the server, it doesn't cause issues, at least
not with OpenSSL 1.0.1f. Other SSL implementations or versions might not be
so forgiving.
