That's fine, I think what you have done looks good, and it doesn't
seem to cause any problems, so I will push it soon (I'm just waiting
on a full test to finish).

The only TODO I see is this:

		/* TODO: don't need to ldb_search again; search in res. */
		ret = ldb_search(ldb, tmp_ctx, &res_site_link, base_dn,
				 LDB_SCOPE_SUBTREE, attrs,
				 "objectClass=siteLink");

which seems to be just an efficiency thing. Do you think the rest of
the algorithm is clear enough for you now?

Cheers, Tridge
