From 909a86af4eb99f5d311d7136cab78dca535ae304 Mon Sep 17 00:00:00 2001 From: Sumit Bose Date: Fri, 31 May 2013 10:52:05 +0200 Subject: Lookup domains at startup To make sure that e.g. the short/NetBIOS domain name is available this patch make sure that the responders send a get_domains request to their backends at startup the collect the domain information or read it from the cache if the backend is offline. For completeness I added this to all responders even if they do not need the information at the moment.
