[Not sure where to report this. So please advise, if there's a more suitable place.]
Dear all,
When upgrading our running freeradius-2.2 configuration for EAP-TTLS to
freeradius-3.0 we followed the guide from http://freeradius.org/version3.html and
almost everything was running in our test environment except one point already
discussed similarly:
http://lists.freeradius.org/pipermail/freeradius-users/2015-March/076365.html
We had the same problem with our wpa_supplicant and Oddyssey clients:
The very last ACK from the client was not well recognized by freeradius-3 with the
same DEBUG message, also see (partly obfuscated radius.debug.txt):
Login incorrect (eap_ttls: Invalid ACK received: 0)
Encouraged from the thread follow-up
http://lists.freeradius.org/pipermail/freeradius-users/2015-May/077614.html we
checked the values returned to the method tls_ack_handler() in src/main/tls.c :
In fact we found for the last ACK:
ssn->info.content_type == 0 (instead of handshake == 22)
ssn->info.handshake_type == handshake_finished (expected 20)
ssn->dirty_out.used == 0
In order to make it work, we patched freeradius-3 like this (also see attachments
tls.c.patch and tls.c.original):
$ diff tls.c.patch tls.c.original
3130,3134d3129
< /* patch needed for many versions of TTLS clients, compare
http://lists.freeradius.org/pipermail/freeradius-users/2015-May/077614.html */
< if ((ssn->info.handshake_type == handshake_finished) && (ssn->dirty_out.used
== 0)) {
< ssn->info.content_type = handshake;
< }

*
* 3.Verifying that the certificate has not been revoked by its
* issuing Certificate Authority, by checking with respect to a
* Certificate Revocation List (CRL).
*
* 4.Verifying that the credentials presented by the certificate
* fulfill additional requirements specific to the application,
