[imp] Errors when logging into imp

[John H. Bennett III]

[long post]

Hello again,

I posted this a couple of weeks ago, but didn't get any responses, so  
I'm at it
again with more info.  Hopefully, someone with the latest version of  
dovecot can give me some additional pointers.

I am getting these errors when I login to imp using dovecot 1.0RC15  
and/or 1.0.0.

I also get a host load of errors in my log when trying to create a folder.
Imp says the folder was created, but it's not there.


Here is what I am currently running:

PHP 5.1.6 (cli) (built: Apr  9 2007 03:37:21)
Copyright (c) 1997-2006 The PHP Group
Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies

Horde - 3.1.4
Ingo - 1.1.3
Turba - 2.1.4
Imp 4.1.4
dovecot 1.0.0

IE 6 - current
Firefox 2.0.0.3

MySQL - 5.0.22

This is my first try with php 5.x, and from searching it looks like this
version of horde should work, so please let me know what other information
is needed from me to assist someone to help out.

-----additional information also posted to the dovecot list.

I am having difficulties trying to get the current stable version of  
horde's imp webmail to work correctly using dovecot 1.0rc15.  I am  
using a pre-release version of SME Server 8 which runs on top of  
CentOS 5.  I have also tried using the 1.0 release of dovecot as well.

What is happenning is that when I login to imp, I don't see any  
folders.  I can create folders in imp which do get created in my  
Maildir directory, but I can't see them.  If I revert back to  
dovecot-0.99.14-1.2, then I am able to see my folders.  I have been  
looking in the wiki at the steps needed to upgrade from 0.99 to 1.0  
and I thought everything had been taken care of, but since things  
aren't working, I have overlooked something.  I also browsed the  
archives and see that others are using hordewith various dovecot 1.x  
releases, so I know it should be possible to get it to work.

My dovecot.conf currently only as the below, which works fine for 0.99:
maildir_copy_with_hardlinks = no

my /etc/pam.d/dovecot has:
more /etc/pam.d/dovecot
#%PAM-1.0
auth       required     pam_nologin.so
auth       include      system-auth
account    include      system-auth
session    include      system-auth

imp servers.php:
$servers['_prompt'] = array(
     'name' => 'Choose a mail server:'
);

$servers['thebennetthome2.com'] = array(
     'name' => 'IMAP Server',
     'server' => 'localhost',
     'protocol' => 'imap/notls',
     'port' => '143',
     'maildomain' => 'test.com',
     'smtphost' => 'localhost',
     'realm' => 'test.com',
     'preferred' => ''
);

php -v

I do get some php errors when logging into horde, and a lot of php  
errors when creating folders that I can post if needed.  I did post my  
issue to the horde list as well, but there has been no answer to date.

Please let me know what other information is needed to assist me with  
fixing this issue.

If you got this far thanks for taking the time,
