Do you use autofs with LDAP? in /etc/init.d/autofs, you should have a line like: echo "$DAEMON $startupoptions $dir $maptype $map $mapoptions $LOCALOPTIONS" | \ sed -e 's/ / /g' -e 's/ / /g' Before that, add: if [ "$maptype" = "ldap" ] ; then mapoptions=`echo $mapoptions | sed 's/, /,/g'` fi Debian, Fedora Core 2, and Red Hat Enterprise 4 ALL have this bug.
