Not sure what you mean by incomplete.  I'll note that certain
URL fields are optional in referrals.  For LDAPv2 referrals,
see <http://www.umich.edu/~dirsvcs/ldap/doc/other/ldap-ref.html>.

We'll be moving away from implicit DNs down the road (for both
LDAPv2 and LDAPv3) as there appears to be a number of implementations
(including OpenLDAP 1) which appear to have problems handling them.

You should be able to create a 'sub' index on 'cn'.  Note that
the test suite does this.

iphostnumber, per schema, doesn't support substrings matching.

Likely the substrings assertion you are making is Undefined.
