-### JWT auth login requires bound audiences on the role
-
-JWT auth roles of type "jwt" require the `bound_audiences` claim to match at
-least one of the JWT's `aud` claims. Prior to 1.16.3, the JWT auth method would
-ignore token `aud` claims that were not a list of strings.

-The consequence of not configuring this correctly means users may not be able
-to login to Vault. To fix the issue, update the role's `bound_audiences`
-parameter to match the `aud` claim on the JWT.
