[imp] Problems with IMP4 imap authentication.

[Patrick S. Roberts]

Hello I am having some rather strange issues with imap4 authentication.  

Server Setup
------------
Ubuntu 7.10 [64bit]
Linux pobox 2.6.22-14-generic #1 SMP Thu Jan 31 23:33:13 UTC 2008 x86_64 GNU/Linux

dovecot  imap
exim4   mta
horde3  framework
imp4  webmail


I can successfully install and connect to horde3, including imap based authentication.

I can go to the /imp/test.php and run a successful test.  Output from that follows.

Attempting to automatically determine the correct connection parameters for your server:

    * Trying protocol imap/notls, Port 143:

    * Trying protocol imap/ssl, Port 993:

          ERROR - The server returned the following error message:

The following configurations were successful and may be used in your imp/config/servers.php file:

    Configuration 1

        'server' => 'localhost'
        'protocol' => 'imap/notls'
        'port' => '143'

    Configuration 2

        'server' => 'localhost'
        'protocol' => 'imap/ssl/novalidate-cert'
        'port' => '993'

    Configuration 3

        'server' => 'localhost'
        'protocol' => 'imap/tls/novalidate-cert'
        'port' => '143'

The following IMAP server information was discovered from the remote server:

    Could not retrieve IMAP information from the remote server.

When I put the following or many other variations in servers.php, none of them work.
--snip--
$servers['imap'] = array(
    'name' => 'IMAP Server',
    'server' => 'localhost',
    'hordeauth' => true,
    'protocol' => '/imap/ssl/novalidate-cert',
    'port' => 993,
    'folders' => '',
    'namespace' => '',
    'maildomain' => 'centtech.com',
    'smtphost' => 'localhost',
    'smtpport' => 25,
    'realm' => '',
    'preferred' => '',
    'dotfiles' => false,
    'hierarchies' => array()
);
--snip--

I get "login failed" even though I know that the username and passwords are correct. [I have verified that they do not require an additional domain on the end of the username]

--snip--

Assumable that the first login is from horde working, then the aborted one is from imp trying to connect.

Any help would be greatly appreciated I have searched and read as much as possible to no avail so far.
