Fri, 10 Apr 2026 13:16:52 +0000 https://bugs.horde.org/ticket/8385 webdav and _username_hook_[from|to]backend When using the _username_hook_[from|to]backend hooks for adding and removing a realm it seems that the _username_hook_tobackend() hook gets not called in all situations when it should. This ends up in getting added the realm twice. This is when trying to access the calender via webdav: https://myserver/horde/rpc.php/testuser@vrealm/testuser@vrealm.ics?server=vrealm (As work around I check in the _username_hook_frombackend() hook if the realm is already attached, but I think that's not the correct fix for this issue) Here are the debug logs: Jun 27 16:23:18 HORDE [debug] [horde] Connected to the following memcache servers:xxx.xxx.xxx.xxx:11211, xxx.xxx.xxx.xxx:11211, xxx.xxx.xxx.xxx:11211, xxx.xxx.xxx.xxx:11211 [pid 18456 on line 127 of "/usr/local/lib/php_horde3/Horde/Memcache.php"] Jun 27 16:23:18 HORDE [debug] [horde] Read session data (id = b0nh4kmoe5nccain26inra5c81) [pid 18456 on line 184 of "/usr/local/lib/php_horde3/Horde/SessionHandler/memcache.php"] Jun 27 16:23:18 HORDE [debug] [] fullname hook called [pid 18456 on line 130 of "/usr/local/apache/htdocs/horde3/horde/config/hooks.php"] Jun 27 16:23:18 HORDE [debug] [] from_addr hook called [pid 18456 on line 54 of "/usr/local/apache/htdocs/horde3/horde/config/hooks.php"] Jun 27 16:23:18 HORDE [debug] [horde] fullname hook called [pid 18456 on line 130 of "/usr/local/apache/htdocs/horde3/horde/config/hooks.php"] Jun 27 16:23:18 HORDE [debug] [horde] from_addr hook called [pid 18456 on line 54 of "/usr/local/apache/htdocs/horde3/horde/config/hooks.php"] Jun 27 16:23:18 HORDE [debug] [horde] fullname hook called [pid 18456 on line 130 of "/usr/local/apache/htdocs/horde3/horde/config/hooks.php"] Jun 27 16:23:18 HORDE [debug] [horde] from_addr hook called [pid 18456 on line 54 of "/usr/local/apache/htdocs/horde3/horde/config/hooks.php"] Jun 27 16:23:18 HORDE [debug] [horde] Max memory usage: 1048576 bytes [pid 18456 on line 339 of "/usr/local/lib/php_horde3/Horde/Registry.php"] Jun 27 16:23:18 HORDE [debug] [horde] Session data unchanged (id = b0nh4kmoe5nccain26inra5c81) [pid 18456 on line 253 of "/usr/local/lib/php_horde3/Horde/SessionHandler.php"] Jun 27 16:26:20 HORDE [debug] [horde] Connected to the following memcache servers:xxx.xxx.xxx.xxx:11211, xxx.xxx.xxx.xxx:11211, xxx.xxx.xxx.xxx:11211, xxx.xxx.xxx.xxx:11211 [pid 18456 on line 127 of "/usr/local/lib/php_horde3/Horde/Memcache.php"] Jun 27 16:26:20 HORDE [debug] [horde] Error retrieving session data (id = m83e4hanv7mj7e04afq7jg3ol3) [pid 18456 on line 174 of "/usr/local/lib/php_horde3/Horde/SessionHandler/memcache.php"] Jun 27 16:26:20 HORDE [debug] [] fullname hook called [pid 18456 on line 130 of "/usr/local/apache/htdocs/horde3/horde/config/hooks.php"] Jun 27 16:26:20 HORDE [debug] [] from_addr hook called [pid 18456 on line 54 of "/usr/local/apache/htdocs/horde3/horde/config/hooks.php"] Jun 27 16:26:20 HORDE [debug] [horde] fullname hook called [pid 18456 on line 130 of "/usr/local/apache/htdocs/horde3/horde/config/hooks.php"] Jun 27 16:26:20 HORDE [debug] [horde] from_addr hook called [pid 18456 on line 54 of "/usr/local/apache/htdocs/horde3/horde/config/hooks.php"] Jun 27 16:26:20 HORDE [debug] [horde] fullname hook called [pid 18456 on line 130 of "/usr/local/apache/htdocs/horde3/horde/config/hooks.php"] Jun 27 16:26:20 HORDE [debug] [horde] from_addr hook called [pid 18456 on line 54 of "/usr/local/apache/htdocs/horde3/horde/config/hooks.php"] Jun 27 16:26:20 HORDE [debug] [horde] Max memory usage: 1048576 bytes [pid 18456 on line 339 of "/usr/local/lib/php_horde3/Horde/Registry.php"] Jun 27 16:26:21 HORDE [debug] [horde] Wrote session data (id = m83e4hanv7mj7e04afq7jg3ol3) [pid 18456 on line 232 of "/usr/local/lib/php_horde3/Horde/SessionHandler/memcache.php"] Jun 27 16:26:28 HORDE [debug] [horde] Connected to the following memcache servers:xxx.xxx.xxx.xxx:11211, xxx.xxx.xxx.xxx:11211, xxx.xxx.xxx.xxx:11211, xxx.xxx.xxx.xxx:11211 [pid 18644 on line 127 of "/usr/local/lib/php_horde3/Horde/Memcache.php"] Jun 27 16:26:28 HORDE [debug] [horde] Error retrieving session data (id = 9mpglfvb8e0v984qt923aqkga5) [pid 18644 on line 174 of "/usr/local/lib/php_horde3/Horde/SessionHandler/memcache.php"] Jun 27 16:26:28 HORDE [debug] [] fullname hook called [pid 18644 on line 130 of "/usr/local/apache/htdocs/horde3/horde/config/hooks.php"] Jun 27 16:26:28 HORDE [debug] [] from_addr hook called [pid 18644 on line 54 of "/usr/local/apache/htdocs/horde3/horde/config/hooks.php"] Jun 27 16:26:28 HORDE [debug] [horde] fullname hook called [pid 18644 on line 130 of "/usr/local/apache/htdocs/horde3/horde/config/hooks.php"] Jun 27 16:26:28 HORDE [debug] [horde] from_addr hook called [pid 18644 on line 54 of "/usr/local/apache/htdocs/horde3/horde/config/hooks.php"] Jun 27 16:26:28 HORDE [debug] [imp] _username_hook_frombackend called for user "testuser -

Or try authenticating at the RPC url with the full username (including realm)? Or have a realm setting in imp/config/servers.php? I only see a single frombackend hook call per request, so the realm must have been added before. Thu, 20 Aug 2009 16:27:35 +0000 https://bugs.horde.org/ticket/8385#t55484 Ping? Tue, 01 Sep 2009 11:10:32 +0000 https://bugs.horde.org/ticket/8385#t55632 Sorry, vacations.... I'm using the following hooks: _prefs_hook_from_addr _prefs_hook_fullname _imp_hook_spam_bounce _username_hook_frombackend _username_hook_tobackend The url is: https://myserver/horde/rpc.php/kronolith/testuser@vrealm/testuser@vrealm.ics?server=vrealm There is no realm set in imp/config/servers.php Unfortunately I can't verify this right now, because since a full Horde cvs update yesterday the apache on my testsystem is segfaulting when trying to login to Horde.

But for now I just removed the TZ relevant parts from Horde.php so that I can at least go on with the original problem of this ticket. I double checked everything, but still the _username_hook_frombackend() hook gets called again on a already "realmed" username: Here is the code for the username hooks that I'm using: if (!function_exists('_username_hook_frombackend')) { function _username_hook_frombackend($userID) { $servers = Horde::loadConfiguration('servers.php', 'servers', 'imp'); $server_key = null; $vrealm = null; foreach ($servers as $key => $val) { if($servers[$key]['server'] == $_SESSION['imp']['server']) { $vrealm = '@' . $key; } } if(empty($vrealm)) { $vrealm = '@' . Util::getFormData('server_key'); } if (substr($userID, -strlen($vrealm)) == $vrealm) { $log_msg = '_username_hook_frombackend called for user "' . $userID . ' - not modifying "'; } else { $log_msg = '_username_hook_frombackend called for user "' . $userID . ' - adding "' . $vrealm . '"'; $userID = $userID . $vrealm; } Horde::logMessage($log_msg, __FILE__, __LINE__, PEAR_LOG_DEBUG); return $userID; } } if (!function_exists('_username_hook_tobackend')) { function _username_hook_tobackend($userID) { $fullusername = split('@', $userID); $log_msg = '_username_hook_tobackend called for user "' . $userID . ' - removing "' . $fullusername[1] . '"'; Horde::logMessage($log_msg, __FILE__, __LINE__, PEAR_LOG_DEBUG); return $fullusername[0]; } } In this code there is a workaround that prevents the addition of the realm if it is already added, but still that's just a workaround.
