RoundCube - MDB2 Error: not found

[Petr Hudeček <pheek zavinac seznam bod cz>]

Dobry den, pokousim se rozjet RoundCube a dostal jsem se s instalaci az po 
Create config a pokud dam vygenerovat config a continue tak mi to napise:

Check config files
main.inc.php:  OK
db.inc.php:  OK
Check if directories are writable

RoundCube may need to write/save files into these directories
temp/:  OK
logs/:  OK
Check configured database settings
DSN (write):  NOT OK(MDB2 Error: not found)

Make sure that the configured database exists and that the user has write 
privileges
DSN: mysql://roundcube:pass zavinac localhost/roundcubemail

Databeze je mysql a generovala se podel navodu:

# mysql
> CREATE DATABASE roundcubemail DEFAULT CHARACTER SET utf8 COLLATE 
> utf8_general_ci;
> GRANT ALL PRIVILEGES ON roundcubemail.* TO roundcube zavinac localhost
    IDENTIFIED BY 'password';
> quit

# mysql roundcubemail < SQL/mysql5.initial.sql

kde jsem nechal heslo password a uzivatel roundcube zavinac localhost, ale 
pokud zadam ten posledni radek

# mysql roundcubemail < SQL/mysql5.initial.sql

tak mi to vypise

# mysql roundcubemail < /var/www/apache2-default/SQL/mysql5.initial.sql
ERROR 1050 (42S01) at line 11: Table 'session' already exists

databaze a nebo nevim co uz, jen doplnim system je Debian Etch a prihlasuji se 
k databazi pomoci
