As I replied in a private posting, you added the "DN" part to the "URI"
parameter when configuring back-ldap; this resulted in
ldap_url_parselist
split your URI in two, with the "dc=com" part being an illegal URI.

Let me reply publicly to leave track of this subtle configuration issue;
there would have been no problem if the URI were URLencoded.
