All Nortel equipment using the Bay software with a revision prior to Version 18.0.2 must upgrade to at least that version. There is a bug in the encoding of the secret passed between the RADIUS server, the NAS gear, and the client: versions prior to the desired revision pass a secret that is encoded purely with MD5, while the RADIUS RFC requires it differently. You will know if you have this problem if you have log file messages relating to invalid Message-Authenticators.
