Zmieniłem z:
//$cfg['Servers'][$i]['auth_type'] = 'cookie';
na
$cfg['Servers'][$i]['auth_type'] = 'cookie';
czyli autoryzacja Cookie powinna działać. Ale nie wiedząc dlaczego nie działa, i nadal jest strona logowania bez żadnych błędów.
Mój config.ini.php z etc/phpmyadmin:
<?php
/**
* Debian local configuration file
*
* This file overrides the settings made by phpMyAdmin interactive setup
* utility.
*
* For example configuration see /usr/share/doc/phpmyadmin/examples/config.default.php.gz
*
* NOTE: do not add security sensitive data to this file (like passwords)
* unless you really know what you're doing. If you do, any user that can
* run PHP or CGI on your webserver will be able to read them. If you still
* want to do this, make sure to properly secure the access to this file
* (also on the filesystem level).
