imp 3.0 - login throws back to login screen

[Ahokas Jukka]

hello,

Having installed imp 3.0 and horde 2.0 from tarballs, I can almost see the 
light at the end of the tunnel. However, the trouble is that the horde & 
imp login screens (login.php) just return me back to the login screen. 
To fix the problem, I have tried a number of things (ref. mailing lists), 
such as editing files "servers.php" and "registry.php"

*** I would be quite grateful if any of you would know where to look for 
the solution. 

- I have installed the whole thing on cs94190.pp.htv.fi 

- the mysql is installed, and I have done 
mysql  < mysql_create.sq
- I can't see any messages on /var/log/messages ... or /var/log/maillog
...even while using the login.php.
- I have tried uncommenting the 2 lines 
(from /www/htdocs/horde/config/registry.php)
// $this->registry['auth']['login'] = 'imp';
// $this->registry['auth']['logout'] = 'imp';
.... still I cannot login.


- the servers.php has lines like so:

$servers['imap'] = array(
    'name' => 'IMAP Server',
    'server' => 'cs94190.pp.htv.fi',
    'protocol' => 'imap',
    'port' => 143,
    'folders' => 'mail/',
    'namespace' => '',
    'maildomain' => 'cs94190.pp.htv.fi',
    'smtphost' => 'cs94190.pp.htv.fi',
    'realm' => 'cs94190.pp.htv.fi',
    'preferred' => ''
);

$servers['cyrus'] = array(
    'name' => 'Cyrus IMAP Server',
    'server' => 'cyrus.example.com',
    'protocol' => 'imap',
    'port' => 143,
    'folders' => '',
    'namespace' => 'INBOX.',
    'maildomain' => 'example.com',
    'realm' => 'example.com',
    'preferred' => ''
);

$servers['pop'] = array(
    'name' => 'POP3 Server',
    'server' => 'cs94190.pp.htv.fi',
    'protocol' => 'pop3',
    'port' => 110,
    'folders' => '',
    'namespace' => '',
    'maildomain' => 'cs94190.pp.htv.fi',
    'realm' => 'cs94190.pp.htv.fi',
    'preferred' => ''
);


..RTFM?

Cheers, I would really appreciate any ideas..
