[Freeipa-users] The concept of sites...

[Steven Jones]

Ah right, yes, one realm.

However how would you password sync with AD?

So say    London.ad.ms.com  and Newyork.ad.ms.com   

With NY as the "head"  

So with london.ipa.unix.com and newyork.ipa.unix.com

Is there still only one winsync agreement?

I see your point with a messy dns infrastructure, however this would happen in the background.

You would still only have one kerberos realm per IPA instance.
