1. Contrary to popular belief "couldn't get it working" is not a
technical error description that would enable anyone to help you solve
your problem.

2. Those instructions are not from the official software documentation
(which doesn't mean they're bad) and expecting people to read 3rd
party documentation only to help you fix a problem you haven't even
described is asking a bit much, IMO.

3. Only you can know whether one entityID will suffice for your use
case or not. Of course you also don't mention anything about the
number or kind of services so it's impossible for anyone else to say.
Follwing Occam's razor a single one should suffice unless you *know*
your use case requires multiple.
(If the IDPs need to be able to differentiate those logical SPs in
order to apply differing policies then you'll likely need multiple
entityIDs for the logical SPs. If you can get away without that avoid
it, of course.)
