I'm also using using application-based authentication over IMP. Any update on this? Wed, 24 Jul 2013 14:58:27 +0000 https://bugs.horde.org/ticket/12432#t79528 I am also facing the issue, for me active sync wont work and it throughs following error "Problem loading mail folders from IMAP server: IMP is marked as authenticated, but no credentials can be found in the session." Wheras IMP is working fine, I am able to login, send and receive email. I have selected authatication by application and selected application is IMP from the GUI configuration. please help! Tue, 06 Aug 2013 19:42:42 +0000 https://bugs.horde.org/ticket/12432#t79793 I've got the same problem from a server where I'm using LDAP auth. I connect LDAP on 1390 port because I have installed it on a Zentyal 2.2 slave machine (mail server). Web Applications and ActiveSync are working fine. But with syncml, all my devices and software clients are failing to sync calendar. I must report that I have another server with a standalone Zentyal configuration, using port 389, and syncml is working correctly.

Horde 5.1.4 under FreeBSD with Blackberry Funambol-Client Tue, 01 Jul 2014 16:55:50 +0000 https://bugs.horde.org/ticket/12432#t84400 Brand new installation of horde, similar issues with SyncML. Client would receive new contacts and calendar items from horde, but anything created or changed client-side would not sync back. Any updates made to previously-synced items on the server side would also not sync to the client. - Horde 5.2.2 (PEAR installation) - Funambol Sync Client 10.1.6 - Outlook 2010 (14.0.7128.5000 x86) Originally had similar 'HORDE [ingo] IMP is marked as authenticated, but no credentials can be found in the session.' in logfiles from previous testing, but now I'm getting the following: ------------------------------ 2014-09-15T14:33:07+00:00 WARN: HORDE PHP ERROR: session_destroy(): Trying to destroy uninitialized session [pid 6180 on line 303 of "/home/xxx/horde/public_html/pear/php/Horde/Session.php"] 2014-09-15T14:33:09+00:00 WARN: HORDE PHP ERROR: session_destroy(): Trying to destroy uninitialized session [pid 6276 on line 303 of "/home/xxx/horde/public_html/pear/php/Horde/Session.php"] 2014-09-15T14:33:10+00:00 WARN: HORDE PHP ERROR: session_destroy(): Trying to destroy uninitialized session [pid 6279 on line 303 of "/home/xxx/horde/public_html/pear/php/Horde/Session.php"] 2014-09-15T14:33:10+00:00 INFO: HORDE Finished sync of database card user bb@xxx.com dev fol-TU9CU1JEQy1NSVMyOmJicm93bjM=.

The Funambol log shows no errors in synchronization, and does record the correct amount of new/changed items in testing. It also doesn't try and re-send anything, even if the items didn't make it into horde in a previous sync, which would seem to indicate that horde is recording the synchronization tokens properly, but it isn't creating/updating the actual items. I'll update here if I find a solution. We want to replace our antique Exchange environment with horde but this is a deal-breaking issue for us as we have a lot of users on Outlook 2010. Mon, 15 Sep 2014 15:45:01 +0000 https://bugs.horde.org/ticket/12432#t85736 I cannot reproduce this with current code. I can sync edited events back from the device to the server just fine. Is anybody still seeing this? Tue, 19 Jan 2016 11:40:46 +0000 https://bugs.horde.org/ticket/12432#t89496 I tried to clone the Horde from AlmaLinux 8 with manual installed PHP 7.4 environment to AlmaLinux 9 with manual installed PHP 7.4 environment. Then, inside AlmaLinux 9 , I encountered the same error - "IMP is marked as authenticated, but no credentials can be found in the session." After a day study, it seems $_SESSION[imp][imap_ob_pass/xxxxxxxxxxxxxxxxxxx] -> become nothing If I manually modified the file - imp/lib/Imap/Password.php inside "public function serialize()" changed from $session->set('imp', self::PASSWORD_KEY . '/' . $this->_id, $this->_password, $session::ENCRYPT); to $session->set('imp', self::PASSWORD_KEY . '/' . $this->_id, $this->_password, 0 ); It seems working again. (the password is stored in PHP session in plain text format.)

If your session is saved as file (e.g. /tmp , etc) , pay attention to its security (esp shared platform). Sat, 10 Jun 2023 04:09:35 +0000 https://bugs.horde.org/ticket/12432#t94131
