I think some of the confusion comes from the default naming of the
accounts. There are two similarly named accounts being discussed:
1: The Linux account that one logs in as to run Rivendell: rd-user (note
the dash in the name).
2: The mysql account that Rivendell uses to interact with the database:
rduser (Note the lack of a dash).

As mentioned above, rduser is the mysql database user that interacts
with the database.
rd-user is the account with an entry in /etc/password and is the Linux
user that logs in to run the Rivendell system. Note that the name
"rd-user" isn't a hard and fast requirement. I've used my regular Linux
account on my test machines.
I haven't set up a multi-host Rivendell system so I'm not sure about
that part of the equation. I would expect that they communicate using a
mysql listener on a specific port, and not via ssl and Linux users.
Similar to an https session on port 443. The Linux user is irrelevant
(it could be a Windows user connecting even). The credentials passed
would be those of the mysql user (rduser). But that's just an
assumption on my part because I haven't really looked into that aspect.
And it may have changed under version 2. I haven't played w/that yet,
so don't know if Fred and company has made significant changes to the
user side of things.

The placement in the rd.conf file in the identity section is an
unfortunate historical artifact. In the same stanza it mentions both
the rduser password used by mysql right above the Linux user ID. One
would assume that the ID and password mentioned in the [Identity] stanza
would refer to the same thing but they don't. It would be hard to
change that though because it would break existing implementations.
So, in a nutshell, you have two accounts:
rd-user:
Linux account
Referred to as Audio-Owner in rd.conf
Exists in /etc/password
rduser:
mysql user used by Rivendell
Password set in rd.conf

More than welcome. I hope that helps clear things up. I'll be away
from a computer for the next couple weeks so if you still have questions
hopefully someone else can chime in...
