It may be boolean to you, but for Exim it's still only a string.
What may have confused is that Exim has different requirements for
"condition" depending on the contet. Conditions in ACLs and routers
require a string, conditions in string expansions require a expansion
condition as listed in
http://exim.org/exim-html-current/doc/html/spec_html/ch11.html#SECTexpcond
(or the combination conditions or{} and and{}, but obviously you were
able to find that by yourself).

So you want the condition to be true if something is returned? Then
all you need to do is turn the result string into a string expansion
condition, in this case by comparing it to the empty string. Like I
already wrote: and { {...} {ne{}{${lookup ldap{...

Well then, good for you. :)
