With a central repository cert management is easier. Besides, it saves
bandwidth. If you put only the URL of the cert in the message, it will
be much shorter.

Usually central LDAP servers are the solution for zillions of users. But
you must make sure that the server side is available when you need it,
i.e. you need two redundant copies. With only ten clients I wonder if
it's worth it...
