+// Persona represents the information used by core to create implicit entity.
+// Implicit entities get created when a client authenticates successfully from
+// any of the authentication backends (except token backend).
+//
+// This is applicable to enterprise binaries only. Persona should be set in the
+// Auth response returned by the credential backends. This structure is placed
+// in the open source repository only to enable custom authetication plugins to
+// be used along with enterprise binary. The custom auth plugins should make
+// use of this and fill out the Persona information in the authentication
+// response.
