Strange. I tried some variations here and discovered that you must use
a mount point with a long name:
/a-long-directory-name/autofs file:/etc/auto.file --timeout=5 --ghost
Aug 27 08:42:39 lotus automount[23185]: lookup_nss_read_map: reading
map file /etc/auto.rect
Aug 27 08:42:39 lotus automount[23185]: lookup(file): file map
/etc/auto.rect missing or not readable
Aug 27 08:42:39 lotus automount[23185]: do_read_map: lookup module file failed
Makes any difference in your setup?
