[pkg-horde] Bug#383715: Can't login to imp4 with imap, although horde works fine.

[Lorenzo Bettini]

I have exactly the same problem and couldn't solve it yet.

These are my packages:

ii  imapproxy                        1.2.4-5                     IMAP 
protocol proxy
ii  php-net-imap                     1.0.3-1                     PHP 
PEAR module implementing IMAP protocol
ii  php5-imap                        5.1.2-1                     IMAP 
module for php5
ii  uw-imapd                         2002edebian1-13             remote 
mail folder access server

ii  horde3                           3.1.3-1                     horde 
web application framework
ii  imp4                             4.1.3-1                     webmail 
component for horde framework

for the moment I cannot change the imap server.

The syntoms are exactly the same of the original post: can login through 
horde but when I go to imp I get, after a long wait an empty redirect.

In particular, when logging to horde these are the messages in the 
system log:

Oct  6 22:34:15 localhost imapd[10477]: connect from 127.0.0.1 (127.0.0.1)
Oct  6 22:34:15 localhost imapd[10477]: imap service init from 127.0.0.1
Oct  6 22:34:15 localhost imapd[10477]: Authenticated user=**** 
host=localhost.localdomain [127.0.0.1]
Oct  6 22:34:15 localhost imapd[10477]: Logout user=**** 
host=localhost.localdomain [127.0.0.1]

and in the horde log:

Oct 06 22:34:15 HORDE [notice] [horde] Login success for **** 
[151.37.72.107] to Horde [on line 90 of "/usr/share/horde3/login.php"]

then when I log to imp I get:

Oct  6 22:35:34 localhost imapd[10518]: connect from ***.***.***.*** 
(***.***.***.***)
Oct  6 22:35:34 localhost imapd[10518]: imaps SSL service init from 
***.***.***.***
Oct  6 22:35:34 localhost imapd[10518]: Authenticated user=**** 
host=***.***.***.*** [***.***.***.***]
Oct  6 22:35:34 localhost imapd[10519]: connect from ***.***.***.*** 
(***.***.***.***)
Oct  6 22:35:34 localhost imapd[10519]: imaps SSL service init from 
***.***.***.***
Oct  6 22:35:34 localhost imapd[10519]: Authenticated user=**** 
host=***.***.***.*** [***.***.***.***]
Oct  6 22:35:34 localhost imapd[10464]: Killed (lost mailbox lock) 
user=**** host=***.***.***.*** [***.***.***.***]

I found the message Killed (lost mailbox lock) in the imap faq: 
http://www.washington.edu/imap/IMAP-FAQs/index.html#7.19 which I quote here:

"This message only happens when either the traditional UNIX mailbox 
format or MMDF format is in use. This format only allows one session to 
have the mailbox open read/write at a time.

The servers assume that if a second session attempts to open the 
mailbox, that means that the first session is probably owned by an 
abandoned client. The common scenario here is a user who leaves his 
client running at the office, and then tries to read his mail from home. 
Through an internal mechanism called kiss of death, the second session 
requests the first session to kill itself. When the first session 
receives the "kiss of death", it issues the "Killed (lost mailbox lock)" 
syslog message and terminates. The second session then seizes read/write 
access, and becomes the new "first" session.

Certain poorly-designed clients routinely open multiple sessions to the 
same mailbox; the users of those clients tend to get this message a lot.

Another cause of this message is a background "check for new mail" task 
which does its work by opening a POP session to server every few 
seconds. They do this because POP doesn't have a way to announce new mail.

The solution to both situations is to replace the client with a good 
online IMAP client such as Pine. Life is too short to waste on POP 
clients and poorly-designed IMAP clients."

so what could be the problem?

previous versions of imp4 used to work fine (the last working version 
used to be imp4_4.0.2-2_all.deb)

any clue please?

thanks in advance
