Can CUCM sync users from multiple domains in different forests?

Answered Question
Apr 23rd, 2010

Hi Guys,

I'm aware that multiple domains synchronization in single forest is  possible.

Unfortunately, I've read several SRNDs and forums and still can't find out if CUCM 6.X is able to sync users from multiple domains in different forests.

I tried it and it failed, unfortunately I've never found any document that clearly states this is not possible.

I only need to authenticate to 1 domain, but I need to sync user from 2 domain.

Is it possible? Any help will be appreciated, thank you.

Your issue is that a synchronization agreement for a domain will not  synchronize users outside of that domain nor within a child domain  because Unified CM does not follow AD referrals during the  synchronization process.

Read the "Additional Considerations for Microsoft Active Directory" section of the SRND here:

http://www.planetcisco.org/en/US/docs/voice_ip_comm/cucm/srnd/7x/directry.html

It discusses sync with multiple AD domains as well as discontiguous namespaces.
