It might be more appropriate to direct these questions to
a general LDAP list such as <ldap@umich.edu>.  If you
believe a revision to the LDAP RFCs is called for, you should
discuss the specification issue on the IETF LDAPbis WG
<http://www.ietf.org/html.charters/ldapbis-charter.html>
mailing list.

A few quick comments...

There is no conflict.   It is RECOMMENDED that servers recognized
all syntaxes specified in Section 6 of RFC 2252 and all syntaxes
specified in Section 6 of RFC 2256.

RFC 2256 does not supercede RFC 2252.  RFC 2251-2256, 2829, and
2830 (and their normative references) comprise the LDAPv3
technical specification.

octetStringMatch is defined in RFC 2256.  authPasswordExactMatch
and authPasswordMatch are defined in RFC 3112.

no comment.
