Spring Security is now authenticating based on a MariaDB database.

Note that passwords are still currently stored in plain text in the db.

I need to add this line:
  <password-encoder hash="sha">
    <salt-source user-property="username"/>
  </password-encoder>
Control-F for "Password Encoder" on this page
