Hi,

I met this issue when trying to download from lynda.com:

The proxy is ok, I just hidden it.

Post the output of youtube-dl -u user -p pass --dump-pages http://www.lynda.com/C-tutorials/Why-smart-pointers/379655/419905-4.html.

Hi,

I gave up to user & password solution and I tried it by using netrc authentication. It worked fine first time and I got to download a video from lynda but beginning with the second time I received the "Session expired" error. I've read about this and there are some solutions but in that cases they use cookies.
In my .netrc file I used: machine lynda:course login USER password PASSWORD. I tried also with machine=lynda but it doesn't work. It seems that the extractor has to be lynda:course. I don't know what is the idea, I just tried with both.
I put here the output:
./youtube-dl --netrc --dump-pages http://www.lynda.com/C-tutorials/Comparison-relational-operators/182674/366595-4.html
WARNING: parsing .netrc: No authenticators for lynda (None, line None)

That is completely different error than one in OP post. Extractor in .netrc must be lynda.

[cristina28]

But with lynda:course it worked first time, it really downloaded the video. I don't know what to do with the expired session error.
Regarding the first error I have a huge output, I don't know how to send, I put a short version here:
./youtube-dl --dump-pages -u USER@DOM.COM -p PSW http://www.lynda.com/C-tutorials/Comparison-relational-operators/182674/366595-4.html

Looks like authentication involves some additional redirect in your case. What are your credentials personal or organization? Can you provide your credentials for test?

[cristina28]

Organization. I'm afraid I'm not allowed. I could try different others tests and come back with the results.

[dstftw]

Organization login is not supported.
