title: Amazon RDS master user permissions
body: <p>I am logging to my amazon RDS through mysql-workbench as my master user. When I go to User and  Privileges in the server administration panel then in the administration roles only the following privileges are marked for my master user:</p>
  
  <p>UserAdmin
  MonitorAdmin
  Custom</p>
  
  <p>When I try to mark the DBManager privilege, I get the following error in the alert box:</p>
  
  <p><strong>Error changing account <code>myuser</code>@<code>%</code>: Access denied for user 'myuser'@'%' (using password: YES)</strong></p>
  
  <p>In terminal, when I do "show grants for myuser", it outputs:</p>
  
  <p><strong>GRANT SELECT, INSERT, UPDATE, RELOAD, PROCESS, SHOW DATABASES, REPLICATION CLIENT, CREATE USER ON <em>.</em> TO 'myuser'@'%' IDENTIFIED BY PASSWORD 'encrypted password here'</strong> |</p>
  
  <p>I  also did:
  <strong>mysql>GRANT ALL ON '%'.* TO myuser@'%';
  but I get the error ERROR 1044 (42000): Access denied for user 'myuser'@'%' to database '%'</strong></p>
  
  <p>myuser is my amazon rds master user.</p>
  
  <p>How can I grant DBManager permission to my master user.</p>
