[SM-DEVEL] Cannot login - disconnects for no reason

[Yves G. <nos...@un...>]

Hello,
I have just updated my Linux kernel to the latest version and rebooted
the system. Afterwards I checked all systems if they still work. But the
Webmailer (SquirrelMail 1.4.7-CVS) doesn't. When I enter my login data,
it just says I need to be logged in to get access. The mail server
(Courier IMAP) didn't log anything unusual, just a connect and a
disconnect. I changed the IMAP port to something I could monitor and
forward to the actual port, to see what SquirrelMail is talking to the
IMAP server. Here's the transcript of the communication:

That's all. SquirrelMail disconnects immediately after connection, for
no obvious reason. What's up there? Why doesn't it work like just
before? Any help appreciated, this is a productive system. I will try to
find it myself, but as I have no clue where to start searching, this may
take me some days that I actually don't have.
