### examples

``` text
<filter test>
  @type ldap_enrich

  ldap_base_dn "dc=test"
  ldap_query "(uid=%{user})"
  ldap_attributes uid:user_uid,mail:user_mail

  cache_enable true
</filter>
```

* use "dc=test" as ldap search base DN
* ldap_query will be interpolated, with %{user} replaced by record['user'], then send the query to ldap
* ldap_attributes will inject uid attributes as user_uid in record, will inject mail attributes as user_mail in record

## Installation
