Hi, the one thing I would change is these two lines:
idmap config * : range = 1000000-9999999
idmap config * : backend = rid
You seem to be ignoring your users :-)
I would have expected to see something like this:
idmap config * : range = 2000-9999
idmap config * : backend = tdb
idmap config STUDIO : range = 1000000-9999999
idmap config STUDIO : backend = rid
