Note, you can make your own config items in the properties file and use
variables if you want to overlay pieces of it...
# ad-dev or ad-prod
mySchool.ad.environment = ad-dev
ldap.pennKiteAd.url = ldaps://$$mySchool.ad.environment$$.school.edu:636
I know this email was about something else, but wanted to mention...

Thanks, Bert. It's not a big deal for us right now since we are omitting
the base DN from the URL and specifying it in the pspng config items. It
allows us to specify the domain component for the subject baseDN since
we have service accounts outside of the people ou. I don't think it's
worth a PSPNG patch, at least not in the short term, unless there is a
need to utilize the property overlays option that you suggested.
