After upgrading to OL 8.1 and replacing all of my 8 IPA servers I

into this particular problem.
Is it right that I need to have an ID range where all DNA ranges have to
fit in? And that the DNA range of each IPA server has to be distinct
from the ranges of the other IPA servers?
I will start by checking each IPA server with
ldapsearch -x -D 'cn=Directory Manager' -W -b 'cn=Posix
IDs,cn=Distributed Numeric Assignment Plugin,cn=plugins,cn=config'
(according to what Rob wrote on his blog some years ago

Not every master has to have a range. Only those masters that you create
users and groups on. The DNA plugin should be smart enough to skip any
conflicting allocations but why press it? It isn't a whole lot of extra
work to manually set things up if you have to do that anyway and you can
sleep better knowing that duplicate values aren't possible.
Yes, it needs to fit within any IPA ranges you have created. You can
have more than one.
Otherwise you could theoretically end up in a conflict with other
ranges, like a trust, which would be bad.
There is nothing constraining what DNA range you set. The IPA ranges are
there for a hint.
