Well, we'll have to wait and see... but likely the exact form of
the DN provided with the ADD operation will be stored in the directory
and that this would be returned by the search (with minimal rewriting
to conform to RFC2253, Section 4). Matching would be done in
normalized space such that alternative quoting/escaping would still
are all the same DN.
I am planning on updating the clients (but not the client SDK)
to fail if an invalid DN is provided. You'll be able to disable
Hence, ldapsearch -b 'cn=foo+++' '(objectclass=*)'
will return INVALID DN without contacting the server. If the
DN is valid (or the check is disabled), the clients will
send the DN "as is" to the server. If the server determines
that the DN is invalid (which the above DN is), it should
return INVALID DN.

We plan on implementing RFC2253 DN requirements.

If the client sends a DN 'foo=bar++' OVER THE WIRE it should expect an
invalid DN (or similiar) error. A client, of course, is free to
accept foo=bar++ from the user and rewrite it into an acceptable
form before submitting the LDAP operation.
