You know that there has to be more than one line in the file?

There is a complete example of a stanza at the bottom of
https://www.postgresql.org/docs/current/static/libpq-ldap.html

In particular, the stanza has to begin with a line in brackets, like
[mydatabase]

Other than that, the LDAP URL looks fine.

You'd have to call it like this:

psql "service=mydatabase"

(Assuming that you named the service control file stanza "mydatabase".)
