We have a customer who has many locations internationally, and one main domain, like "customer.com". But they are using sub-domains, like germany.customer.com, austria.customer.com.
We have deployed two presence servers, and more are to come. These servers are in different sub-domains, with the consequence that you have to configure federations between then and, thus, cannot add buddies by an LDAP search, which is too cumbersome for most users.The have to add the buddies by hand.
The solution we are looking at is to add a sub-domain just for these servers, like presence.customer.com, and if all the presence servers are in this sub-domain, federations are no more needed.
Is such a design feasible? Do you see pitfalls or possible problems in the future?
And if this is a good idea, should we just add all the UC-Servers to this sub-domain (e.g. CUCM, Meetingplace, Unity, Unity Connection)?
Thanks for your consideration,
So you are saying, if all the users where in one AD, then they search the LDAP directories and add buddies in?
Can you simply add the root domain to the search base? If the AD users in CUPS that searchs the directory has access to each of the sub domains, it should be able to "fetch" anything in the sub domains. (searches etc)
Michael may have some more info for you also. (in the forum here)
But I like the idea also of the Presence domain....
Federation is really only when you have multiple CUCM clusters. They will then relay presence status, etc between the CUPS servers.
