Secret, undocumented, or sparsely documented function might as well be non-existent function. Sparse doc produces even sparser usage. One example from about 18 months ago: The customer just wanted the HMC logs sent to a central repository. Lots of people affirmed that it should be able to be done. None could find enough doc to get it to work.
I dealt with lots of different customers in my previous job. In almost every case the HMCs were the purview of the MVS sysprogs. Most have never gone beyond SYSPROG, or clones of SYSPROG. And the senior MVS guy(s) aren't going to take informal doc/advice from their VM counterpart when it comes to "their HMC".... So if Alan knows, and even posts it to the list here, that doesn't carry much weight with that senior MVS guy. And months from now who would think of searching the VM listserv for doc on the "hardware" HMC. If the HMC can really do such things easily (well, as easily as other Linux systems), then it needs to be usably documented in the HMC books. (Don't get me wrong... Alan and most other IBMers are both willing and good at sharing what they know. But it's not official published doc.)

There is some capability to dynamically provision HMC IDs via LDAP using user templates and/or patterns. I'm getting details from Product Engineering, as the published information is, shall we say, sparse. (Read: Pretty much non-existent.) The HMC also has complete audit facilities, including the ability to manually and/or automatically upload the logs to another system. If customers have requirements for HMC functionality, they need to make those requirements known.
