No more than having them both self-singed.

No more likely than someone asking the same questions about actually using
self-signed certs at all.

It would be more fantastic if you could actually provide more details of your
environment, up to now we've not known that you have more than one server, and
we don't know how your clients are set up.
For example, if you have multiple servers and multiple clients, you really are
defeating the point of SSL and increasing your administrative burden by not
creating a CA cert.
Now, if you need to re-create a cert, you will have to update the "CA cert" on
all clients. If you add another server, you will have to append the new
server's cert to the "CA cert".
However, IMHO, this is starting to get off-topic even for this list, almost
none of this is specific to OpenLDAP, it would be equally applicable to
Apache/Firefox3 or IIS/IE7 (with their new draconian cert validation
