When I tried this, the config file reading routines complained of
extraneous characters after 'ldap', so I suppose I'll have to go with the
two director system. I suppose it doesn't add all that much overhead,
since exim caches the result of ldap_bind_s, and would have to call
ldap_url_search twice whether it was in two directors or part of an or{}
construct.
