Strange error when exporting to Mediawiki


I’m trying to use the Mediawiki extension to export text to my Mediawiki (version 1.21.1). However, after entering my credentials, I always get the error “username and/or password incorrect” (translated from Dutch…).
Because it is a corporate wiki, my wiki is closed, so everyone needs to log in before content can be seen / edited.
The only error I can see in the apache logs are (error_log) :

[Mon Nov 17 13:30:55 2014] [error] [client] PHP Warning: ldap_start_tls(): Unable to start TLS: Can’t contact LDAP server in /var/www/wiki/extensions/ldapauthentication/LdapAuthentication.php on line 593

Additional information:
The wiki is connected to our company’s Active Directory LDAP. Logging in from the wiki login page (using the same credentials) is no problem.


  1. When specifying the wiki location in LibreOffice, is it sufficient to specify the “normal” wiki URL ?
    Like: http://myserver/wiki/, or do I need to specify the location of the login page as well ?
    I tried entering http://myserver/wiki/index.php?title=Special:Login, or something like that, but that didn’t work.
  2. I searched the internet before coming here, and people that hav had the same error say you have to
    enter the following line in your /etc/openldap/ldap.conf : TLS_REQCERT never.
    Doesn’t help either…

Anyone out there that has seen this error using the wiki extension ?
Any help is more than welcome.
