When I set my research base for the whole root.
DC = mydomain, DC = com, DC = br
Show me all users in Active Directory.
But I have to look at the following group
Telefonia_Cisco cn =, ou = Global!, ou = Groups, ou = EscritorioCentral, ou = mydomain, dc = mydomain, dc = com, dc = br
Is it possible?
Based on your second screen shot, it appears you are trying to establish a user search base starting with the actual AD group CN. This will not work.
Yes, in 7.1.3 the only way you can customize the LDAP filter is to modify the table directly using the AXL/SOAP API. The AXL Query Toolkit is one pre-built interface to the API. In 8.0 and later you will have a nice GUI to make the mod. But until then, this is what you have.
I suggest you read the Cisco SRND for CUCM 7.x (www.cisco.com/go/srnd). There is a whole section on LDAP integration that will help you grasp the basics. There are some fundamental components I don't think you have accounted for.
Your only option is to add an LDAP filter. This is easy in UCM 8.0 and later; however, there is no GUI for this in earlier versions. You essentially have to filter against a specific attribute. The most common example is filtering on the ipPhone field not being null which was covered in this thread: https://supportforums.cisco.com/message/1068263
