Probably not a coincidence that CDC-Ns1auth starts with CDC-Ns1. Sounds
like it's using CDC-Ns1 as a prefix to match hostnames, rather than as
an actual hostname.
Looks like there's config setting in 3.0 called use_regexp_matching
which might control that. Perhaps in your old config file that was
somehow turned on. (Or perhaps not defined at all, and on is the default.)
Who knows what other old settings you're inheriting too. It's probably
best for you to scrap your old config, and start fresh with a new 3.0
config file, then adopt it to your needs (i.e., point it to whatever
custom definitions/definition-files you've created).
