[imp] failed logon from imp front-end

[Geoff Sweet]

I have tried very hard to follow through with trouble shooting this, but
haven't gotten very far.  Google and the archives had some hints, but
nothing that solved my problem.

When I go to www.domain.com/horde/imp it presents me with the logon
screen.  I attempt to logon and it gives me a pop-up error:

": could not be found. Please check the name and try again."

However if I go to the /horde/imp/test.php and enter the exact same info
there, it authenticates properly and shows the test messages that I have
in the inbox.

Now for my configuration.  This is PHP 4.2.3, latest Imp and Horde,
latest courier imap, vpopmail on qmail, and OpenBSD 3.2 OS.

I thought that this maybe a config problem.  So I altered Imp so that it
displays a list of servers to attach to.  No love there, same error.  So
here is my imp/config/servers.php as it sits now:

$servers['_prompt'] = array(
    'name' => _("Choose a mail server:")
);
 
$servers['imap'] = array(
    'name' => 'Whootis.com Hosting',
    'server' => 'localhost',
    'protocol' => 'imap',
    'port' => '143',
    'folders' => '',
    'namespace' => '',
    'maildomain' => '',
    'smtphost' => '',
    'realm' => '',
    'preferred' => ''
);


Like I said the very confusing part about this is that the test.php
works fine, but the front-end login doesn't.  The imap server isn't SSL
hence the imap/notls, but the site to connect to it is SSL.

I hope I have provided enough info for someone to give me a hand.  This
product looks awesome and I can't wait to start letting my customers use
it!
