Thu, 09 Apr 2026 22:37:19 +0000 https://bugs.horde.org/ticket/7340 Login screen reappears in right frame after successful IMAP login I'm using Horde 3.1.6 with IMP 4.1.6 and am using composite authentication to sidestep the MIMP (1.0.2) double login issue as recommended on this Horde Wiki page: http://wiki.horde.org/MIMPHowTo The only difference is that I'm authenticating Horde with a secure LDAP server, and IMP with an IMAP server, like this: /* composite configuration for horde and mimp */ $conf['auth']['params']['drivers'] = array( 'horde' => array('driver' => 'ldap', 'params' => array('hostspec' => 'ldaps://[hidden]', 'basedn' => 'ou=[hidden],dc=[hidden],dc=[hidden]', 'version' => '3', 'ad' => true, 'uid' => 'uid', 'encryption' => '[hidden]', 'newuser_objectclass' => array('shadowAccount', 'inetOrgPerson'), 'objectclass' => array('uid'), 'filter_type' => 'objectclass', 'password_expiration' => 'no' )), 'mimp' => array('driver' => 'application', 'params' => array('app' => 'mimp'))); $conf['auth']['params']['loginscreen_switch'] = '_horde_select_loginscreen'; if (!function_exists('_horde_select_loginscreen')) { function _horde_select_loginscreen() { require_once 'Horde/Browser.php'; $browser = new Browser(); if ($browser->isMobile()) { return 'mimp'; } return 'horde'; } } /* IMP servers.php configuration */ $servers['imap'] = array( 'name' => 'IMAP Server', 'server' => '[hidden]', 'hordeauth' => true, 'protocol' => 'imap/ssl/novalidate-cert', 'port' => 993, 'maildomain' => '[hidden]', 'smtphost' => '[hidden]', 'smtpport' => 25, 'realm' => '', 'preferred' => '', ); The LDAP (AD v. 3) and IMAP servers contain the same usernames and passwords, because we're in the process of converting the mail server to LDAP authentication, so I have IMP configured to use Horde authentication (see 'hordeauth' line above). All of this works fine most of the time, but occasionally users who access /imp directly get presented with the Horde left sidebar frame, indicating a successful LDAP login, and a login screen in the right frame, indicating an unsuccessful IMAP login. If they click on "Mail" in the left sidebar without logging in again, however, they are able to access their IMAP Inbox. It appears that either a) the login process isn't waiting for a successful login message from the IMAP server before reporting a login failure (i.e. a timeout is occurring), or b) the first IMAP login attempt actually does fail, for whatever reason, and Horde retries the IMAP login when a second attempt is made to access the user's IMAP mail, which subsequently succeeds.

This doesn't seem to be a Horde problem, and Horde 3.1.x is only supported for security fixes anymore anyway. Thu, 18 Sep 2008 10:49:28 +0000 https://bugs.horde.org/ticket/7340#t48994
