Imp 2.2.6 (and previous) problem

[Michele Albrigo]

Hi all,
I've a big problem with Imp. I've used Imp 2.2.4 since last week, then
decided to update the entire webserver (hardware and software). On the
previous configuration everything worked fine, while now there's something
broken, and I can't understand where it is.

My previous configuration was:
Apache 1.3.19+mod_ssl
Php 4.0.5
Imp 2.2.4 and Horde 1.2.4
Kernel 2.2.19 with some patches...
MySQL 3.23.33

Now I'm running:
Apache 1.3.20+mod_ssl
Php 4.0.6
Imp 2.2.6 and Horde 1.2.6
Kernel 2.4.6 + getrewted 1.5 security patch.
MySQL 3.23.39

What happens:
I can start apache and test horde (horde/test.php3) and everything is
perfect. If I try to use IMP (horde/imp/index.php3), the page renders fine
but if I try to log in to the IMAP server it locks up and timeouts. After
that, if I get back to horde/test.php3 the session test goes timeout (but
the session instance is created succesfully). If I stop and restart
apache, the session test works again, but if I try to use IMP it locks up
again.

I get no error messages in apache/logs/error_log and my syslog says login
failed. I have no access to the IMAP server I must read mail from, so I
can't see its logs. I've tried reading mail from another server I've
configured (which works with IMP 2.2.5 and horde 1.2.5) and it is ok. I've
tried copying configuration files from that server and I always get the
same resut (timeout and sessions don't work anymore). I've also tried
installing IMP 2.2.5, but it locks up the same way.

I've configured PHPLIB to store session data in shared memory, so that I
should never lose the active_session table in mysql database (I've lost it
two months ago and it took me a long time to understand where the problem
was). I've also set up the database as if I used it to store them.
Sessions work fine (unless I use IMP). If I set up PHPLIB to use mysql as
session data storage, counter doesn't increment, it just stay at 1
silently with no errors (and mysql doesn't complain about wrong passwords
and so on).

Horde reports that my PHP supports everything (except for PostgreSQL, but
I don't need it). phpinfo() says that IMAP is supported (with SSL too).
Other web applications I use on the server (phpweblog, phpnuke and others)
work fine with no problems at all.

I've tried to open my IMAP server from Horde Imp demo site and it works
right.

My php configure command is this:

./configure --with-apxs=/usr/local/apache/bin/apxs
--with-openssl=../openssl-0.9.6b/ --enable-bcmath --enable-calendar
--enable-ftp --with-ldap=/usr/local/openldap
--with-mysql=/usr/local/mysql --enable-versioning --enable-track-vars
--with-gd --with-mm=/usr/local/lib/mm --with-jpeg-dir=/usr/lib/
--with-png-dir=/usr/lib/ --enable-sysvsem --enable-sysvshm
--enable-sockets --with-zlib --with-bz2=/bin/ --with-ttf=/usr/X11R6/lib/
--with-libpdf=../../incoming/libpdf_php.so
--with-imap=../imap-2001.BETA.SNAP-0107221451/ --with-imap-ssl

IMAP c-client compiled with no errors and so did PHP. I've also tried to
do a ldd libphp4.so, and every linked library is ok.

That's all. Since everything seem to be ok, it works everywhere else but
here... ...where am I doing wrong? Is there something else I should give a
look to?

Another (much smaller) question: I need to set up an IMAP-SSL webmail,
with LDAP addressbook search. LDAP should work fine (it seem to be
supported by my php and it worked on my previous installation). What about
IMAP-SSL? Where is it configured?

Thank you in advance for your help!
