Hello Personnel

I just install the zimbra, I think it's perfect the resources it is wonderful!

Well, but I am having a problem for integrating it with my base of users from Active Directory (AD).

Someone could help me or give me some tips?
Already tried by documents, but still could not make the integration.

I throw all requests, but when I make the test I have the following response:

Code:
Soap: Receiver 
System failure: unable to search gal
