Some quick system information: I'm running Arch linux with all the latest software, LDAP is configured and (more or less) working.  The autofs maps are stored on an LDAP server and these maps are used by a couple of hundred Ubuntu 14.04 boxes.Here is the /etc/autofs/autofs_ldap_auth.conf configuration:<autofs_ldap_sasl_conf    usetls=yes    tlsrequired=yes    authrequired=yes    authtype=EXTERNAL    external_cert=etc/openldap/ca-cert.pem/>on running# systemctl start autofsautofs dumps core:Jan 12 14:55:33 lizard systemd[1]: Starting Automounts filesystems on demand...Jan 12 14:55:33 lizard systemd[1]: Started Process Core Dump (PID 16463/UID 0).Jan 12 14:55:33 lizard systemd[1]: autofs.service: Control process exited, code=exited status=1Jan 12 14:55:33 lizard systemd[1]: Failed to start Automounts filesystems on demand.Jan 12 14:55:33 lizard systemd[1]: autofs.service: Unit entered failed state.Jan 12 14:55:33 lizard systemd[1]: autofs.service: Failed with result 'exit-code'.Jan 12 14:55:33 lizard systemd-coredump[16464]: Process 16458 (automount) of user 0 dumped core.

Autofs started with no problems when /etc/autofs/autofs_ldap_auth.conf was set to:<autofs_ldap_sasl_confusetls=notlsrequired=noauthrequired=no/>(i.e. the package default).
