EAP session problem

Hi guys,
I'm using PEAP/MSCHAPV2 and OpenLDAP password backend (and Samba3) to
provide wpa2-enterprise authentication to wifi users inside an high school
(with OpenWRT access point).
Everything has been working very well for one year. Wonderful!
Three days ago something very strange has started to happen.
Wifi users can't create a TLS tunel (windows, linux, android) to provide
the authentication.
I didn't touch the configuration files in the last few months. Nothing has
changed. The CA certificate is valid.
This is my server.
