I added a new cobbler setting to ensure that all client commands are forced to use the localhost instead of the server setting.  In my environment we have cobbler nodes where we provide a remote server for that entry or the VIP in the cluster (active/standby cobbler nodes).  This is causing commands like cobbler sync from completing as they can attempt to connect to the VIP.  The setting defaults to off, but can be turned on if you want to force connections to the localhost.

Let me know if you have any questions.
