First, as the three parts of any rewrite rules are
whitespace-separated, you need to put the whitespace-containing second
part inside double quotes.

Secondly, to make the ldap query safe, you need to use
${quote_ldap:$local_part} where it now says just $local_part.

We do similar address rewriting here; the rewrite rules look like
this:

------------------------------------------------------------------------
# Rewrite user address to user's default address.
*@*    \
  "${lookup ldap {LDAP_BASE?defaultMailAddress?sub?\
    (mail=${quote_ldap:$local_part@$domain})}\
     {$value}fail}"                        hq
------------------------------------------------------------------------
