Means you have built --enable-wrappers but don't have a /etc/hosts.allow
file. Create one and leave it empty to eliminate the error. Or you
might want to put in the hosts that should be accessing the LDAP server,
slapd: localhost .mydomain.com
to allow localhost and everything in the mydomain.com domain.

Not sure. Could be a side affect of the above error. If fixing the
above does not clear it up, I'd recommend you upgrade to the latest
released version of OpenLDAP.

Perhaps someone can volunteer such a shell script. It's likely been
asked before. Try searching the mailing list archives.
