another step towards schema aware normalization: ava sorting in rdns; now by defining USE_LDAP_DN_PARSING both the new dn parsing and the server side normalization is used. There might be, every now and then, a flaw mostly due to naive normalization of pseudo-dn (thinking about some acl/regex stuff and so)
