SCOPE_ONELEVEL is used on wildcard dns searches, but onelevel searches currently have a performance problem related to GUID indexing, so this patch changes the search scope to SCOPE_SUBTREE. In this case, as the onelevel and subtree sets of records are roughly the same, and the query is matching against the DN itself, we don't believe there's any benefit in using SCOPE_ONELEVEL over SCOPE_SUBTREE. The onelevel performance problem will be fixed separately later, but in the meantime this solves the DNS performance problem.
