There is no difference.  Both:
	ldap://server
	ldap://server/

specify invalid searches (a subtree search of a NULL DN is invalid)
but are not invalid URLs.

	ldap://server/??base refers to the rootDSE
	ldap://server/??one refers to top-level entries that might
		by held by the server such as "c=US", "dc=COM"
	ldap://server/??subtree is invalid search

from this:
	ldap://server
	ldap://server/

and represent invalid searches.  However, namedref says
such URLs, when returned as protocol referrals imply that
the client should use the base/DN of the operation which
returned the referral.

Since a server would not ever return a referral "ldap:///??base";
for any operation, no ambiguity exists.
