Just to clarify, in order to use the "Search" capability then you have to have LDAP. There is no access to the traditional "Corporate Directory" in CUCM unless you create a LDAP and hook CUPS to it.

Correct. If you want to search or IM any other CUPC subscriber, you have to use and LDAP source.

When I was testing it, I found that odd also. But it makes sense from a security point, or if you wanted to limit functionality for certain subscribers.

Understood, so is there a quick way to dump the CUCM directory to get it into AD without doing the LDAP sync in CUCM? The client I am asking for is not LDAP integrated with AD currently.

You can simply do a BAT export of the current users in CUCM. It will spit out to a CSV file. It will everything you see on the users properties page in CUCM.

You can then import this into AD using a script. (not quite clear on that part, but I know you can)

I had a client that did not have AD setup yet. (Novell shop). But they did have Unity setup as Voicemail only. For a temp solution for CUPS/CUPC, we used the Unity domain and it worked fine. The client understand that they will eventually have to move the LDAP lookup and authentication to the production AD environment when they are ready.
