title: $cfg['Servers'][$i]['users'] ... not OK
body: <p>I recently upgraded from phpMyAdmin 3.5.3 to 4.1.4 and I'm having problems with some of the configuration storage settings.  At least, it <em>seems</em> that I'm having problems.  Maybe this is expected behavior but I want to be sure.</p>
  
  <p><strong>My Procedure:</strong></p>
  
  <ul>
  <li>Downloaded and extracted new phpMyAdmin and copied it to /srv/www/htdocs/  (The previous version is still there but uses a different directory name - I didn't want to remove it until I got the new version working)</li>
  <li>Used the setup web GUI to create a new config.inc.php.  I know that it says to copy the old one but I figured there might be new fields since this is a new major version.  Also, when I was done, I verified that the old config.inc.php and the new one have the same values for identical fields.  I then copied it to the phpMyAdmin root.</li>
  <li>Ran examples/create_tables.sql and noticed that it did create some new tables in the phpmyadmin database.</li>
  <li>Logged in successfully and most features seem to be working fine.</li>
  </ul>
  
  <p>Here's what I'm not sure about.  It gave me the message: "The phpMyAdmin configuration storage is not completely configured, some extended features have been deactivated. To find out why click here."  And when I click there it has the following complaints:</p>
  
  <pre><code>$cfg['Servers'][$i]['users'] ...    not OK [ Documentation ]
  $cfg['Servers'][$i]['usergroups'] ...   not OK [ Documentation ]
  Configurable menus: Disabled
  
  $cfg['Servers'][$i]['navigationhiding'] ...     not OK [ Documentation ]
  Hide/show navigation items: Disabled
  </code></pre>
  
  <p>I figured it was because there were not yet any entries for those in config.inc.php but even when I enter those lines with blank values into config.inc.php, I still get the same messages.</p>
  
  <p>Maybe I'm misinterpreting this, but to me "not OK" indicates some kind of an error, not just that the value is being intentionally left blank.  Is that correct?  Did I miss something?  Or is that phpMyAdmin's way of saying that it's not currently in use but that I have nothing to worry about?</p>
  
  <p>All the other configuration storage features are marked as "OK" and "Enabled" - it's just these new ones (which weren't in 3.5.3) that are "not OK."</p>
  
  <p>Is something wrong or is this the way it should be if I don't want to use those features?</p>
