[horde] LDAP issue: DN for user not found

[Martin Hoefling]

Hello Folks,

since upgrading to Horde 5.2.0, I get the following log messages:

[horde] DN for user not found [pid 6446 on line 886 of 
"/opt/horde/pear/php/Horde/Ldap.php"]

My ldap and auth section in config/conf.php looks like this:

$conf['ldap']['hostspec'] = 'ldaphostname;
$conf['ldap']['tls'] = false;
$conf['ldap']['version'] = 3;
$conf['ldap']['user']['uid'] = 'uid';
$conf['ldap']['user']['objectclass'] = array('shadowAccount', 
'inetOrgPerson', 'posixAccount');
$conf['ldap']['user']['filter_type'] = 'objectclass';
$conf['ldap']['bindas'] = 'user';
$conf['ldap']['useldap'] = true;
$conf['auth']['admins'] = array('martin');
$conf['auth']['checkip'] = true;
$conf['auth']['checkbrowser'] = true;
$conf['auth']['resetpassword'] = false;
$conf['auth']['alternate_login'] = false;
$conf['auth']['redirect_on_logout'] = false;
$conf['auth']['list_users'] = 'input';
$conf['auth']['params']['basedn'] = 'dc=myorg,dc=com';
$conf['auth']['params']['scope'] = 'sub';
$conf['auth']['params']['ad'] = false;
$conf['auth']['params']['uid'] = 'uid';
$conf['auth']['params']['encryption'] = 'ssha';
$conf['auth']['params']['newuser_objectclass'] = array('shadowAccount', 
'inetOrgPerson', 'posixAccount');
$conf['auth']['params']['filter'] = '(objectclass=shadowAccount)';
$conf['auth']['params']['password_expiration'] = 'no';
$conf['auth']['params']['driverconfig'] = 'horde';
$conf['auth']['driver'] = 'ldap';
$conf['auth']['params']['count_bad_logins'] = false;
$conf['auth']['params']['login_block'] = false;
$conf['auth']['params']['login_block_count'] = 5;
$conf['auth']['params']['login_block_time'] = 5;

Binding to LDAP is allowed anonymously, write access to some of the 
params only by the actual user / ldap admin.
Any ideas what could be wrong here?

Best
