Hello My system: FreeBSD 8.2-RELEASE FreeBSD 8.2-RELEASE #0: Fri Apr 29 15:58:00 CEST 2011 martin@acsvfbsd04:/usr/obj/usr/src/sys/GENERIC i386 acsvfbsd04# pkg_info|grep sasl cyrus-sasl-2.1.23 RFC 2222 SASL (Simple Authentication and Security Layer) cyrus-sasl-saslauthd-2.1.23 SASL authentication server for cyrus-sasl2 In /etc/rc.conf I have: saslauthd_enable="YES" saslauthd_flags="-a kerberos5" In /var/log/auth.log I get always: May 4 08:44:24 acsvfbsd04 saslauthd[38396]: do_auth : auth failure: [user=martin] [service=imap] [realm=] [mech=kerberos5] [reason=krb5_verify_user_opt failed] All the Kerberos5 stuff is working because I can use sasltauthd -a pam (which use the FreeBSD modul pam_kerb5). So it's not a Kerberos related problem. PS: On a amd64 plattform the same setup is working... So it seems to be 32 bit problem... Any ideas? Regards, -- Martin Schweizer schweizer.martin@xxxxxxxxx
