i don't find slapd.pid

Hi,

am creating a database ldap on squeeze. the configuration was ok. due to some errors adding new entries, following the guide "Mastering OpenLDAP", page 96, i deleted with this command:

rm __db.* *.bdb log.*

then i succesfully added two ldif files using slapdadd. i started slapd with

/etc/init.d/slapd start.

i launching ldapsearch but the answer ii can't contact the server. i checked with ps -aux about the slapd process but i didn't find it. i checked in /var/run/slapd/ and there is not slapd.pid.

have you got idea about this? what could i do?

thanks
