Well, that's completely up to you!

Obviously the dynamic assignment has the advantage of lower administrative
overhead.

Manual provisioning with idmap_ad is useful if you already have assigned
UIDs and GIDs to your users (from, for example, an existing NIS deployment)
and want to preserve them as they are migrated to Active Directory, and/or
if you have deployed software that supports the Services for UNIX
schema (*).

(*) such software includes PADL's nss_ldap module and NIS/LDAP Gateway,
    and the NIS server included with Services for UNIX itself
