We have a distributed system which consists of an Identify Provider (idP) which handles user authentication and authorization. The idP associates a UUID with a user and issues JWT Access Tokens which contain the UUID as a JWT claim. We also have a MySQL database (DB) which stores user meta-data. The UUID used to identify the User by the idP is stored in the DB, this allows us to establish a connection between the idP user and their DB meta-data.
