Have you solved the issue already?
I'm facing a similar problem. In my current project we have a huge AD. When i use the Active Directory connector, Sense automatically assigns a (reference) name to the Connector. In this case 'EUROPE'. But i wish to distinguish between the different countries by setting up a connector with a filter for that country so that i can refer to a specific connector to set the rules.
But when i create a connector for, let's say, the Netherlands where all the different departments\groups from the Netherlands are specified it still names the connector 'EUROPE'. I tried using the 'Genereric LDAP' connector and named it to 'Holland' but then there is no match with the users since they are a member of 'EUROPE' and 'Holland' is not known in the AD.
Assigning rights to each individual group or user is not an option because there are just to many and the user base is to dynamic.
