The London/newyork dns sub-domains would be used for looking up srv records for

base would still be the ipa.domain.com.
Sync with AD would still be done between ipa.domain.com<-> ad.domain.com.

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.

Hi,
I think AD sort of does this which they have now backed away from?
From my very limited understanding having sub-domains/realms seems to be
counter-productive....in that trying to do cross-realm trusts/passwords/user
info becomes a
nightmare?
I know somehow I have to get unix.vuw.ac.nz to talk to staff.vuw.ac.nz and
student.vuw.ac.nz in
a winsync (password) agreement, I dont know even if that's possible? Yet with
a flat domain to
flat domain its easy?

Subject: [Freeipa-users] The concept of sites...
Hi,
Has there been given any thought to the concept of sites within IPA to
improve cross-site implementations? This should be easy to implement as you are
already using
DNS
SRV records to locate the ldap/kerberos servers.
E.g.
Site: Boston
Site: London
Create a subdomain of the IPA dns domain named _sites, and a subdomain
of _sites for each site.
Boston._sites.ipa.domain.com would contain the srv entries for IPA
servers in Boston: _ldap._tcp in srv 0 100 389 boston-ipa-server1
_ldap._tcp
in srv 0 100 389 boston-ipa-server2 .....
London._sites.ipa.domain.com would contain the srv entries for IPA
serers in London: _ldap._tcp in srv 0 100 389 london-ipa-server1
_ldap._tcp
in srv 0 100 389 london-ipa-server2 ....
Now point the client's DNS "search" entry to point to the local site
first, then search the full name space: Boston client's /etc/resolv.conf: search
Boston._sites.ipa.domain.com ipa.domain.com
London client's /etc/resolv.conf:
search London._sites.ipa.domain.com ipa.domain.com
The main ipa.domain.com could still contain srv records for all IPA
servers, or selected IPA servers at the central hub.
I know I can do this manually within the DNS managment in IPA today,
however it would be a lot easier to maintain "Sites" within the IPA webui/cli.
*blink* ;)
What's your thoughts on this?
Regards,
Siggi
