Do I need to configure director?

Hi,

I'm configuring a farm of dovecot proxies redirecting users to backend 

servers. The decision of which backend server is used for a user is based in its ldap account information.

In my previous configuration I was using an inherited director 

configuration in these proxy servers, but now I was wondering that because the decision is made according to user information, I don't need to run director. Do it?

Is there any advantage of running director in this scenario?
