such requests didn't return an error.

*Details* +

|
|
parameter is deprecated and will be removed in {es} 8.0.0.

|
|
locally.

|
*Impact* +

==== Changes to built-in users
|
|
|
|
[float]
|
|
===== The `kibana` user has been deprecated in favor of the `kibana_system` user
|
|
|
|
The `kibana` user was historically used to authenticate {kib} to {es}.
|
|
The name of this user was confusing, and was often mistakenly used to login to {kib}.
|
|
This has been renamed to `kibana_system` in order to reduce confusion, and to better
|
|
align with other built-in system accounts.
|
|
|
|
If your `kibana.yml` used to contain:
|
|
[source,yaml]
|
|
--------------------------------------------------
|
|
elasticsearch.username: kibana
|
|
--------------------------------------------------
|
|
|
|
then you should update to use the new `kibana_system` user instead:
|
|
[source,yaml]
|
|
--------------------------------------------------
|
|
elasticsearch.username: kibana_system
|
|
--------------------------------------------------

[[builtin-roles-changes]]
|
|
==== Changes to built-in roles
|
|
|
|
[float]
|
|
===== The `kibana_user` role has been deprecated in favor of the `kibana_admin` role
|
|
|
|
Users who were previously assigned the `kibana_user` role should instead be assigned
|
|
the `kibana_admin` role. This role grants the same set of privileges as `kibana_user`, but has been
|
|
renamed to better reflect its intended use.
