(ITS#5628) dereferencing user with translucent overlay

When using the translucent overlay, if one tries to use set syntax in an ACL or
ACI rule, in order to dereference the bound user, like in the example below,
then the user's entry is fetched from the local database only.
Example <who> clause:
by set="user/eduPersonOrgUnitDN & [ou=someunit,dc=someorg,dc=somecountry]"
If the 'eduPersonOrgUnitDN' attribute has not been modified it will not be found
in the local database. I believe it would be better if the remote database was
also checked, like when a search operation is performed against the overlay.
I found the problem was due to that acl_set_gather2 tries to fetch the attribute
directly from the backend, but the translucent overlay does not support this, so
the backend is used instead. I've attached a patch which makes acl_set_gather
always use an internal search operation to fetch the attribute, instead of
I've also tried to hack the translucent overlay so that it would support the
bi_entry_get_rw callback but I haven't been able to provide something that would
even satisfy me. I suppose I would have to use some sort of callback mechanism
like translucent_search_cb but I haven't figured it out yet.
