Identity Secret Backend
Name: identity
The Identity secret backend is the identity management solution for Vault. It
internally maintains the clients who are recognized by Vault. Each client is
internally termed as an Entity. An entity can have multiple Personas. For
example, a single user who has accounts in both Github and LDAP, can be mapped
to a single entity in Vault that has 2 personas, one of type Github and one of
type LDAP. When a client authenticates via any of the credential backend
(except the Token backend), Vault creates a new entity and attaches a new
persona to it, if an entity doesn't already exist. The entity identifier will
be tied to the authenticated token. When such tokens are put to use, their
entity identifiers are audit logged, marking a trail of actions performed by
specific users.
Identity store allows operators to manage the entities in Vault. Entities can be created and personas can be tied to entities, via the ACL'd API. There can be policies set on the entities which adds capabilities to the tokens that are tied to entity identiers. The capabilities granted to tokens via the entities are an addition to the existing capabilities of the token and not a replacement. Note that the additional capabilities of the token that get inherited from entities are computed at request time. This provides flexibility in controlling the access of tokens that are already issued.
This backend will be mounted by default. This backend cannot be unmounted or remounted.
API
