Actually, I found the winbind problem : I was using samba 3.0.28 which is bugged on using winbind on a samba PDC. I upgraded to 3.0.33 and now winbind is working correctly, meaning I can authenticate a user using ntlm_auth --username=xxx and I have "NT_STATUS_OK: Success (0x0)". However, it is still failing when I try to authenticate with dovecot and ntlm. Here is the log I have :

Actually, I'm not sure which user is passed in, as it is Outlook that send the NTLM hash to dovecot. Is there a way to track ? Is it the auth_username_format which is incorrect ? My parameters are : auth_ntlm_use_winbind = yes auth_username_format = %n auth_winbind_helper_path = /usr/bin/ntlm_auth Best regards, Cédric Laruelle -----Message d'origine----- De : dovecot-bounces+laruellec=aiderdonner....@dovecot.org [mailto:dovecot-bounces+laruellec=aiderdonner....@dovecot.org] De la part de Cédric Laruelle Envoyé : lundi 11 mai 2009 10:46 À : dovecot@dovecot.org Objet : Re: [Dovecot] NTLM configuration No, I haven't. The problem is I find nowhere explanations on how to configure winbind to authenticate against samba. All configurations I found were to configure it on AD. In samba docs, I found "Winbind is targeted at organizations that have an existing NT-based domain infrastructure into which they wish to put UNIX workstations or servers", but that's not my case ... If you have any clues where I could find or ask the info it would be mulch appreciated.

"user not authenticated: NT_STATUS_NO_LOGON_SERVERS" suggests to me that you havent got a working winbind setup.
