title: Authenticating users with Spring security against two user-services
body: <p>I am very new to Spring security and my problem is as follows:</p>
  
  <p>I have a <strong>member</strong> mysql table that contains information about the website's members, including their usernames, passwords and roles. So far so good: I can use this table to configure a <code>&lt;jdbc-user-service</code>.</p>
  
  <p>However I also want to have a super user that is not going to be in the <strong>member</strong> table.</p>
  
  <ol>
  <li>Is it possible and recommended to have this super-user in an in-memory user repository and therefore mix jdbc user service with in-memory user service? If so how?</li>
  <li>If <strong>1.</strong> is not possible perhaps I can have a second mysql table called for instance <strong>moderator</strong>. Then what sort of sql query would I need to authenticate against these two tables?</li>
  </ol>
