ACL issue with dnattr

[Michael Donnelly <donnelly@sendmail.com>]

I've included the following ACL into my slapd.conf file.

access to dn=".*,ou=exampleGroups,dc=([^,]+),dc=([^,]+)"
       by dnattr=owner write
       by * read

access to ou=exampleGroups,dc=([^,]+),dc=([^,]+)"
       by dnattr=owner write
       by * read


With this, I've found no problems editing an existing entry under 
ou=exampleGroups,dc=foobar,dc=com when bound with the DN of an owner. 
(No other ACL grants the bound connection any rights other than read.)

However, I am unable to delete the entry when bound as the owner.  I'm 
running OpenLDAP 2.0.23

Is this a bug?
Is there a work-around?
