=== Role Mapping APIs

The Role Mapping API enables you to add, remove, and retrieve role mappings.

==== Request

`GET /_xpack/security/role_mapping` +

`GET /_xpack/security/role_mapping/<name>` +

`DELETE /_xpack/security/role_mapping/<name>` +

`POST /_xpack/security/role_mapping/<name>` +

`PUT /_xpack/security/role_mapping/<name>`

==== Description

NOTE: The API requires that each role mapping have a distinct name. The name is
 used solely as an identifier to facilitate interaction via the API, and does
 not affect the behavior of the mapping in any way.

For more information, see
{xpack-ref}/mapping-roles.html[Mapping Users and Groups to Roles].

==== Path Parameters

`name`::
 (string) The distinct name that identifies the role mapping. If you do not
 specify this parameter, the Get Role Mappings API returns information about all
 role mappings.


==== Request Body

The following parameters can be specified in the body of a PUT or POST request
and pertain to adding a role mapping:

`enabled` (required)::
(boolean)  Mappings that have `enabled` set to `false` are ignored when role
mapping is performed.

`metadata`::
(object) Additional metadata that helps define which roles are assigned to each
user. Within the `metadata` object, keys beginning with `_` are reserved for
system usage.

`roles` (required)::
(list) A list of roles that are granted to the users that match the role-mapping
rules.

`rules` (required)::
(object) The rules that determine which users should be matched by the mapping.
A rule is a logical condition that is expressed by using a JSON DSL.


==== Authorization

To use this API, you must have at least the `manage_security` cluster privilege.


==== Examples

[[security-api-put-role-mapping]]
To add a role mapping, submit a PUT or POST request to the `/_xpack/security/role_mapping/<name>`
endpoint:

[source,js]
--------------------------------------------------
POST /_xpack/security/role_mapping/administrators
{
  "roles": [ "user", "admin" ],
  "enabled": true, <1>
  "rules": {
     "field" : { "username" : [ "esadmin01", "esadmin02" ] }
  },
  "metadata" : { <2>
    "version" : 1
  }
}
--------------------------------------------------
// CONSOLE
<1> Mappings that have `enabled` set to `false` will be ignored when role mapping
    is performed.
<2> Metadata is optional

A successful call returns a JSON structure that shows whether the mapping has
been created or updated.

[source,js]
--------------------------------------------------
{
  "role_mapping" : {
    "created" : true <1>
  }
}
--------------------------------------------------
// TESTRESPONSE
<1> When an existing mapping is updated, `created` is set to false.

[[security-api-get-role-mapping]]
To retrieve a role mapping, issue a GET request to the
`/_xpack/security/role_mapping/<name>` endpoint:

[source,js]
--------------------------------------------------
GET /_xpack/security/role_mapping/administrators
--------------------------------------------------
// CONSOLE
// TEST[continued]

A successful call retrieves an object, where the keys are the
names of the request mappings, and the values are
the JSON representation of those mappings.
If there is no mapping with the requested name, the
response will have status code `404`.

[source,js]
--------------------------------------------------
{
  "administrators" : {
    "enabled" : true,
    "roles" : [
      "user",
      "admin"
    ],
    "rules" : {
      "field" : {
        "username" : [
          "esadmin01",
          "esadmin02"
        ]
      }
    },
    "metadata" : {
      "version" : 1
    }
  }
}
--------------------------------------------------
// TESTRESPONSE

You can specify multiple mapping names as a comma-separated list.
To retrieve all mappings, omit the name entirely.

[source,js]
--------------------------------------------------
# Retrieve mappings "m1", "m2", and "administrators"
GET /_xpack/security/role_mapping/m1,m2,administrators

# Retrieve all mappings
GET /_xpack/security/role_mapping
--------------------------------------------------
// CONSOLE
// TEST[continued]

[[security-api-delete-role-mapping]]
To delete a role mapping, submit a DELETE request to the
`/_xpack/security/role_mapping/<name>` endpoint:

[source,js]
--------------------------------------------------
DELETE /_xpack/security/role_mapping/administrators
--------------------------------------------------
// CONSOLE
// TEST[continued]

If the mapping is successfully deleted, the request returns `{"found": true}`.
Otherwise, `found` is set to false.

[source,js]
--------------------------------------------------
{
  "found" : true
}
--------------------------------------------------
// TESTRESPONSE
