I wonder if it would be possible to have more on-deck ranges. Could
dnaNextRange be multi-valued, and when the low-water mark is hit the
would pick one of them?

Not at the moment, this is a single valued attribute type:

attributetypes: ( 2.16.840.1.113730.3.1.2129 NAME 'dnaNextRange' DESC
'DNA ran
  ge of values to get from replica' SYNTAX SINGLE
  -VALUE X-ORIGIN '389 Directory Server' )

But it is a good question for 389-ds guys, it would be a good
extension to the
DNA plugin and would prevent us from not-loosing the range when there
is no
master with empty dnaNextRange. But maybe there is a strong reason why
this was
made single value...

If you make it multi-valued, then you probably want to have some sort of
ordering to the values . . .

I don't know. We don't have a whole lot of control of ordering when DNA gets a range, so I think that holes in the range happen now, so I wouldn't have a problem with lack of control.

Ok. Please file an RFE ticket. There are some code changes that we will need to make to DNA to make next range take multiple values.
