How to setup pmlogger, so it used authentication when talking with pmcd?

Solution Verified - Updated -

Issue

When accessing pmcd over the network, for example with pmrep -h <remote-system> <metrics> or with pmlogger, then some Performance Metric Domain Agents (pmda's) who are used by pmcd are not offering the full amount of data. So we want to setup authentication for pmcd, and then have pmlogger use that authentication to access pmcd, to get access to the full amount of data. How to do that?
