The symlink isn't very useful. It'll just cause extra LDAP connections
to be created, since that userdb is used only for iteration anyway and
iterations are always executed in their own separate processes with
separate LDAP connection.

You could put all of the userdb_* stuff to mail_* settings, but since
you're using userdb prefetch there has to be one at least. :) So maybe
just keep userdb_home there and put the rest to dovecot.conf:

mail_location = mdbox:~/mdbox
mail_uid = vmail
mail_gid = mail
