Duplicate attributeType

[Jason Lixfeld <jason+lists.openldap@lixfeld.ca>]

So I'm not quite sure what's going on here.  I try to start slapd, I  
get a "Duplicate attributeType error, but there is only one attribute  
in all included schema which is using that OID.  The actual entry cn  
attribute type entry in core.schema looks like this:

attributetype ( 2.5.4.3 NAME ( 'cn' 'commonName' )
        DESC 'RFC2256: common name(s) for which the entity is known by'
        SUP name )

More stuff below...

root@oob1# /usr/local/etc/rc.d/slapd.sh start
Starting slapd.
/usr/local/etc/openldap/schema/core.schema: line 82: Duplicate  
attributeType: "2.5.4.3"

Any ideas?
