I've defined the server links and the requisite administrators. I've also -- by way of experimentation as much as anything else -- set up the fifth server to subscribe to the same config pushed to the other servers. I'm now finding that, whenever I try to export a server directly to this fifth server, I get a bunch of error messages in the logs. Some of them are relatively spurious[1]; others, however, are of concern[2].
Does anybody know where I can find a supplier of soft brick walls? *sighs* Looks like the problem's solved: I forgot to activate the policy sets on the fifth server. Talk about your trivial fixes ...
Please excuse me; I have some banging of heads (mostly my own) to do.
