And that also works if LDAP_HOST is defined with a value other than
"localhost"?

Just asking since the answers to this SO question claim that Java
itself does not support this (though Apache commons configuration
seems to when using the "env:" prefix on the variable name, which
doesn't match your example either):

But maybe Shibboleth's own code does this, I haven't checked.
