What version of OpenLDAP are you using?

A bug similar to this was corrected in 2.4.18:
http://www.openldap.org/its/?findid=5942

If you're using an older version, this should still work fine so long as 
the URL in the -h option to slapd exactly matched the URL in serverID 
(make sure the all slashes are present, etc).

Preferably, use the latest release, though, to avoid other such bugs now 
fixed :)
