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.
So. If my ID range for the IPA domain is
I could set the DNA ranges like that:
DNA Range ipa1
DNA Range ipa2
DNA Range ipa3
DNA Range ipa4
DNA Range ipa5
DNA Range ipa6
DNA Range ipa7
DNA Range ipa8
Do you agree?
Do I have to use ldapmodify or could I use
ipa-replica-manage dnarange-set ipa1.mydomain.at 1246600001-1246620001 ?
