.. To use PKI authentication, assign the writer role, plus any other roles that are

{es}.
<2> The example shows a hard-coded password, but you should store sensitive
values in the <<keystore,secrets keystore>>.

If you've configured the {kib} endpoint, also specify credentials for
authenticating with {kib}. For example:

* To use Public Key Infrastructure (PKI) certificates to authenticate users,
configure the `certificate` and `key` settings. These settings assume that the
distinguished name (DN) in the certificate is mapped to the appropriate roles in
the `role_mapping.yml` file on each node in the {es} cluster. For more
information, see {xpack-ref}/mapping-roles.html#mapping-roles-file[Using Role

[[feature-roles]]
=== {beatname_uc} features that require authorization

After securing {beatname_uc}, make sure your users have the roles (or associated
privileges) required to use these {beatname_uc} features. Note that some of the
roles shown here are {xpack-ref}/built-in-roles.html[built-in], and some
are user-defined.

restrictive access.
