It is unclear (to me, of course) how, according to RFC 3687, this rule
could be used to match portions of a DN.  I expect that the rdnMatch rule
would allow filters like "(seeAlso:rdnMatch:=cn=All Staff)" in the test
suite to match those entries whose seeAlso attribute contains "cn=All
Staff,ou=Groups,dc=example,dc=com".  In order to do so, I had to do some
hacking to slapd; I'll post a patch later, when I regain access to my
laptop, with my weekend homeworks :), if anyone can confirm my
expectations.

Also, it is not clear (to me, again) if RFC 3687, when referring to RDN,
indicates the LAST rdn (i.e. the leftmost), or ANY rdn inside a DN.
