Subject: [PATCH] s3-winbindd_ads: use the reconnect methods instead of the rpc
 methods directly

Some of the ads methods just point to the rpc methods.
This makes winbindd_ads use the reconnect methods instead of
calling the rpc methods directly in order to prevent
negative cache entries for e.g. name_to_sid, when the dc
has closed the connection without sending a reset.
