Re: [Evolution] EWS NTLM auth not working



Hello,

 

I spent a little more time investigating the issue. I took a look in to the source code of libsoup and I think it calls winbind's ntlm_auth binary without password with the --use-cached-creds option only. And if that does not work, it makes some own computations. I am no programmer, so I might be wrong. Nevertheless, I tried to join the domain and login with pam_winbind to be able to use the cached credentials. I tried to call ntlm_auth manually and it worked and so did login in Evolution. I think that libsoup itself might not actually support NTLMv2, maybe just NTLM2, or the implementation is broken. Anyway, I post it for information. If there would be anyone willing to take a look on this, I would appreciate. Using Thunderbird with EWS plugin for calendars is rather difficult.

 

Regards

j2ev

Hello,

 

in case some other desperate soul crosses over this topic, I still wasn't able to resolve this issue. It just looks Evolution / libsoup / ntlm_auth is not for some reason sending NTLMv2, but just NTLMv1. I asked in libsoup mailing list as well, but it is rather dead or had no luck.

Hi Milan,

 

thanks for your input. Yes, I do have ntlm_auth binary. But I've already tried to rename it, even purge winbind from the system, which provides it. The behavior was still the same. Well, I will try libsoup list then.

 

Thanks
