r17542: In using ldb_map, I ran across some very odd behaviours when we search
for objectClass=xyz. The code has been warning at me 'no covert_operator set', and indeed this is the case. (It then proceeds to strip this as a search expression) In this commit, I have implemented a convert_operator for objectClass, by pretending it is a simple MAP_CONVERT operator for the search requests. I also have changed the logic for when we should bail out. I can only see reason to bail out on the search if we have both local and remote trees. How can a remote-only search be un-splittable? Andrew Bartlett (This used to be commit 656e58672c357121647a080400fcab4e5d30b46b)
