OpenLDAP's extended matching rule names are case-sensitive:

(:caseIgnoreMatch:=foo) works, (:caseignorematch:=foo) finds nothing.
(:2.5.13.2:=foo) also works.
(:dn:caseIgnoreMatch:=foo) works,
(:DN:caseIgnoreMatch:=foo) says 'ldap_search_ext: Bad search filter (-7)'.
(uid:dn:=foo) works, (uid:DN:=foo) finds nothing.
