Problems with NTLM proxy authentication

[Strahlex]

I have a problem with the NTLM proxy we use in school. YAST proxy configuration won't work, it just says authentication error.
We have to login with the user in DOMAIN\user style and a password, in Firefox it works.
I'll post the error log tomorrow.

curl --proxy-ntlm --proxy-user DOMAIN\\user:password --url www.google.at --proxy http://10.0.3.1:8080/

works fine, but how do I set up something like this for the whole system?

I have the same problem. Can anybody help me? How set Yast-Proxy to use NTLM authentication?

[Strahlex]

Can anybody help please?

If the curl command works (is important) and you're using either SuSE 11.x then go to YAST > Network Services > Proxy

If curl doesn't work, I'm pretty sure you're SOL... In my network I had to turn off Windows Domain authentication at my MS ISA proxy to allow non-browser HTTP connections like Yast Online Update.
