can i define what indexers and search heads can connect to a license master up front before they have tried to connect?
i.e do i have to create a pool that states ANY INDEXER can connect? wait for them to connect and then change it to Specific indexers only?
What will happen if none of the pools allow "ANY INDEXER" and they point a live indexer to the license master when it has no pool allocated?
You should be able to add indexers to license pools from the command line - see http://docs.splunk.com/Documentation/Splunk/latest/Admin/LicenserCLIcommands
