Slurpd doesn't appear to be working.

["Nick Bernstein" <nbernstein@frontbridge.com>]

I'm trying to get slurpd to push updates to a slave ( am I getting that
backwards, because the name would imply pulling, not pushing ). Anyway, I'm
not getting any errors when I start slurpd, but it doesn't seem to be doing
anything either.  

[ foo@ldap-master ~] sudo slapd -d 10 -f /etc/openldap/slapd.conf 
<< I changed some entries in the master ldap directory >>
<< nothing shows up in logs >>
