--- Comment #6 from Anastasius Focht focht@gmx.net 2013-05-04 15:14:11 CDT --- Hello Fabian,
you should fix that:
--- snip --- err:winediag:SECUR32_initNTLMSP ntlm_auth was not found or is outdated. Make sure that ntlm_auth >= 3.0.25 is in your path. Usually, you can find it in the winbind package of your distribution. --- snip ---
(install the samba/winbind package for your distro)
Regards
