substring filters using DN attributes ?

[sanjay jain <sanjay.jain@software.com>]

It looks like from standard LDAP schema that
substring matching is not allowed for DN syntax
attributes.  E.g. for 'member' attribute.
Does it mean from http://www.ietf.org/internet-drafts/draft-just-ldapv3-rescodes-02.txt
section 5.2.2.1.3 that if an LDAP server gets a filter
like: member=*dc=org1,dc=com
it should return 'inappropriateMatching' error code ?

thanks
