Subject: Re: OpenSSH 3.5p1 Remote Root Exploit for FreeBSD

This seems to be in libopie rather than sshd or libpam and happens
when the username is longer than OPIE_PRINCIPAL_MAX.  I'm not sure
exactly where inside libopie it is, but commenting out
seems to prevent it.
prevents usernames longer than OPIE_PRINCIPAL_MAX from being accepted
by pam_opie.

usually comes from bad judgement.
