Per-objectclass attribute mapping with slapd-meta

["Daniel Montero Motilla" <damonmo@gmail.com>]

Hi, i'm trying to accomplish this kind of attribute and objectclass
mapping with slapd-meta:

map objectclass inetOrgPerson User
map attribute cn givenName
map objectclass groupOfNames Group
map attribute cn name

But it seems that attribute mapping affects attributes of all
objectclasses, so I obtain a "duplicate attribute mapping" error with
lines 2 and 4. How can I establish a per-objectclass attribute mapping
so I don't obtain that error?

Thanks in advance!

Dani.
