Creating and Authorizing a User on the OpenSearch Dashboards

Prerequisites

The security mode has been enabled for the OpenSearch cluster.

Parameters

**Table 1** Parameters for creating and authorizing a user on Kibana
Parameter	Description
Permission	Single permission, for example, creating an index (for example, indices:admin/create)
Action group	A group of permissions. For example, the predefined SEARCH action group grants roles permissions to use _search and _msearchAPI.
Role	A role is a combination of permissions and action groups, including operation permissions on clusters, indexes, documents, or fields.
Backend role	(Optional) Other external roles from the backend such as LDAP/Active Directory
User	A user can send operation requests to Elasticsearch clusters. The user has credentials such as username and password, and zero or multiple backend roles and custom attributes.
Role mapping	A user will be assigned a role after successful authentication. Role mapping is to map a role to a user (or a backend role). For example, the mapping from kibana_user (role) to jdoe (user) means that John Doe obtains all permissions of kibana_user after being authenticated by kibana_user. Similarly, the mapping from all_access (role) to admin (backend role) means that any user with the backend role admin (from the LDAP/Active Directory server) has all the permissions of role all_access after being authenticated. You can map each role to multiple users or backend roles.

You can customize the username, role name, and tenant name in the OpenSearch Dashboards. Chinese characters are not allowed.
