You can use LDAP to search for an alternative mail attribute, and specify a default location using 
mail_location. In your example; mail_location = /var/vmail/%u. Then use one LDAP config file to override the 
mailbox location if the LDAP database specifies a maildir location.

By the way, aren't userdb's searched sequentially? Try switching those userdb's to make the one with the group 
lookup go first. LDAP users will always match the userdb without group lookup.
