Hi Thilo, I worked a lot on this subject these two last days. But I only experimented Kerberos, and Samba/Winbind/NTLM. Why don't you want to install Samba? It's easier to make it work than a Kerberos system (from what I saw). You have to install Samba, configure it, install winbind, bind on a AD domain with an administrator, and finally configure Apache to use this auth. You also need to be sure that your java container won't try to authenticate itself. See: http://adldap.sourceforge.net/wiki/doku.php?id=seamless_authentication if you haven't found this before. I don't know any other solution without using samba or krb. Good luck! Guillaume Fenollar XWiki SAS 2012/9/11 Schmidt, Thilo (VZ) <Thilo.Schmidt(a)vdek.com>

Hi everyone, Some of my users get a "Failed to execute the [velocity] macro" error in the "Recent Changes" section after update to version 4.2-MILESTONE-2. Others don't... I really don't know how to resolve this. I thought about a "privileges" probleme since only some users get this error at loging but how can I resolve it There is a similar error here in the xwiki-based XWiki website ! http://playground.xwiki.org/xwiki/bin/view/Main/RecentChanges The full error stack is in the attachement Thanks for your help Regards Ce message et toutes les pi?ces jointes (ci-apr?s le < message >) sont confidentiels et ?tablis ? l'intention exclusive de ses destinataires.

Hi Thilo, As Guillaume Fenollar says, NTLM will require Microsoft protocols, hence the need for Samba. But if your objective is just to implement single sign on on Linux you can go with other standards: - CAS (more simple) - Kerberos (complicated) You just need to setup a CAS Server (there are open source implementations see http://www.jasig.org/cas) You need an Apache HTTPD CAS module You then can use XWiki's AppServer Trusted Authentication You can probably find a CAS Server that can authenticate on an LDAP Server Ludovic 2012/9/12 Schmidt, Thilo (VZ) &lt;Thilo.Schmidt(a)vdek.com&gt;om>: -- Ludovic Dubost Founder and CEO Blog: http://blog.ludovic.org/ XWiki: http://www.xwiki.com Skype: ldubost GTalk: ldubost
