I think the wiki sql configuration was written/tested by someone who got
the same errors, but ignored them.. You need to provide also a mapping
for this. Maybe something like:

map {
	pattern = shared/shared-boxes/anyone/$from
	table = anyone_shares
	value_field = dummy

	fields {
		from_user = $from
	}
}

or maybe to your existing table (just don't have a user called
"anyone"):

map {
	pattern = shared/shared-boxes/user/anyone/$from
	table = user_shares
	value_field = dummy

	fields {
		from_user = $from
	}
}

I think the dict is rebuilt sometimes when ACLs change (or if
dovecot-acl-list file is rebuilt for some other reason). This code isn't
really optimized yet and it might be rebuilding them unnecessarily..
