In our use of LDAP, the ldap_default_servers option contains what I believe
Philip intended it to contain, namely a list of the LDAP servers to be used
by queries elsewhere in the configuration which do not specify servers.

I haven't seen anyone put the query itself into ldap_default_servers (but I
haven't seen all working Exim configurations.

>From the (4.6.1 spec--the one I have handy on my desktop machine):

ldap_default_servers:
This option provides a list of LDAP servers which are tried in turn when an
LDAP query does not contain a server. See section 9.14 for details of LDAP
queries. This option is available only when Exim has been built with LDAP
support.

No mention of a query going in there.

We haven't had a need to have expansion of this option. That doesn't mean
there is no need of it.
