Random 401

[danbord]

Hello,

I tried with many different versions, but I started to have weird behavior where I get some random 401 errors when running my UI test on my development computer. Those tests runs fine on our integration server, but locally some services often get a 401 but passes randomly too. Everything runs fine when I use the website.

I tried with cypress-ntlm-auth v1.3.0, 2.0.0m 2.0.1 and the latest 2.0.2. Same behavior.

I tried with cy.ntlmSso() and cy.ntlm() fucntions. Same behavior.

I tried with cypress 3.6.1, 3.5.0 and 3.4.1.

My 2 services are all running locally under IIS with localhost:8080 and localhost:8088. My angular web app is localhost:4200 with node (started with ng s -o).

Here is my debug log if it can help :

Hi @danbord - first, big thanks for going the extra mile and testing your case with different versions of both the plugin and cypress before submitting!

It's a bit confusing because according to the logs, everything is fine. I see no indication of failed authentication (which would be the plausible cause for 401's being sent to the client).

How does those failed requests look in the browser? Can you see if they really go through the proxy?

Also - for how long has this been happening? What else might have changed in your environment, since it used to work fine for you?

[danbord]

Hello Bjorn, thanks again for your help. Heres 2 screenshots you can see what happens. Actually we are implementing cypress on another project, nothing is really different from the other one except that maybe we use more intensively two differnet api (8080 and 8088) for our rest calls

[bjowes]

Ok, that’s a bit clearer. If you could click on one of the requests in the cypress log details about the request are printed to the console log of the browser. Could you do that for a successful request and for a failing request, and try to compare the details?

If you want to post them here, please expand the details at least one level. I’m not sure what we are searching for so I need to see as much as possible.

[danbord]

Sure, here's the result of one OK (200) and one Not Authorized (401) for the /AccessRights endpoint.

By the way I made some more tests and if I remove all the calls to /usage/navigation in my code (which is on another website (localhost:8080), /AccessRights (which is on localhost:8088) is always working! Is it possible that cypress-ntlm-auth is mixing authentication between both webservice websites (localhost:8080 and localhost:8088 in my example)?

200

401

[bjowes]

Thanks - seeing the details of the 401 response you received narrowed down the possibilities in my code quite a bit. I have a feeling that this could be related to sockets staying open between tests. I don't think that the sockets are mixed up by ntlm-proxy, but I can see scenarios where the handshake won't be initiated if a previously authenticated socket is reused after a cy.ntlm() call has updated the config for the host.

Could you try adding a cy.ntlmReset() call in a beforeEach statement? The reset removes the current config, and it also purges all existing connections.

[danbord]

Well I’m only running one test so the cy.beforeEach is only called once. If you still think it’s relevant I’ll do the test tomorrow morning (I’m off work and cannot get access to my computer at the moment)

[bjowes]

Hmm, but in the logs you sent in the initial post I see that the NTLM host configurations are updated multiple times so I just assumed that was from multiple tests. Sure, that could occur within a single test too, but I would guess that isn't very common. Either way, try adding a cy.reset before you call cy.ntlm (given that you call cy.ntlm for all the hosts, otherwise you lose the config). No rush from my side, just trying to help you out :)

[danbord]

I added the cy.ntlmReset() just before my login fucntion in the beforeEach and it did not help :/

[bjowes]

Ok, thanks for trying. I think I will need to make a special build with extra logging for you to get to the bottom of this. How urgent is this issue for you?

One thing more to check:

• In the console logs for the 401, expand the response (just above the XHR) so I can see the headers and body
• Do a manual request to the same API address (since it is a GET request just type it into a Chrome browser that isn't running on Cypress) and look at the response headers and body of the 401 you receive then (without the ntlm-proxy in between)

[danbord]

Hey Bjorn, first of all, just thank you for helping me out. Understand that no matter how urgent this issue is for us, you support on you spare time, so please I don't want you to feel any pressure in any way! ;)

That issue is pretty annoying, and we must fix that in the coming week or so because we need those tests to work before we go in prod. In the meantime I can temporarily deactivate the "usage/navigation" calls to allow us to write tests locally though.

The AccessRights (which is a GET) seems to always be working when I type the url in a new tab (in same cypress context browser)

Here's a couple screenshots for XHR's:

/usage/navigation (POST on 8080) - 204 and 401 side by side

/AccessRights (GET on 8088) - 200 and 401 side by side

[bjowes]

What I'm looking for is a request to the API resulting in 401 without using ntlm-proxy. I need to know if your API returns a body in such a response (headers would also help) to determine which path the traffic passes through my proxy. There are some cases where the body is passed along as is, and other cases where the body is dropped.

To perform such a request, maybe it would be easier if you use a tool like Postman. Or simply reconfigure your local API to prevent access for your account, and use Chrome (without Cypress!) to access it. We need to avoid automatic authentication which Chrome will do for you if your own user has access to the API.

[bjowes]

Since we seem to be working in different timezones, here are a couple of modifications you can do to the cypress-ntlm-auth code to get better logging - if you can add these to the code in the node_modules folder where you are running cypress you can get the logs directly and I don't need to make a dedicated release (which I can't do until later). Please use plugin version 2.0.3 for the modifications.

In the file dist/proxy/ntlm.manager.js, line 128 - current code

if (authState === ntlm_state_enum_1.NtlmStateEnum.NotAuthenticated) {
  // NTLM auth failed (host may not support NTLM), just pass it through
  return callback();
}

change to

if (authState === ntlm_state_enum_1.NtlmStateEnum.NotAuthenticated) {
  // NTLM auth failed (host may not support NTLM), just pass it through
  this._debug.log('NTLM authentication failed, invalid state.');
  return callback();
}

In the file dist/proxy/ntlm.proxy.mitm.js, line 168 - current code

res.headers['connection'] = 'close';

change to

res.headers['connection'] = 'close';
self._debug.log('Received 401 from NTLM handshake, sending 401 with body to client. Client socket ' + ctx.clientToProxyRequest.socket.remoteAddress + ':' + ctx.clientToProxyRequest.socket.remotePort);

In the file dist/proxy/ntlm.proxy.mitm.js, line 184 - current code

ctx.proxyToClientResponse.end();

change to

ctx.proxyToClientResponse.end();
self._debug.log('No response in NTLM handshake callback, sending empty 401 to client. Client socket ' + ctx.clientToProxyRequest.socket.remoteAddress + ':' + ctx.clientToProxyRequest.socket.remotePort);

And then run your test with debug logs and submit them.

[danbord]

I updated my screenshots on my last post to be more readable.

Here's a 401 result for my AccessRights call with postman (since the desktop app of postman is not ntlm friendly I can get a 401 easily). By the way Body is empty when I get a 401

I'll update the code to add the logging like you asked :)

[danbord]

By the way, I do not see anything in the log that we just added.

Just to be sure I was updating the right thing, I added a this._debug.log('NtlmManager constructor'); in the NtlmManager constructor and I see it in the log, so everything should be fine.

Thanks! So, I think I know what the issue is. After studying the logs more closely it is clear that client sockets are reused for different targets. I didn't think clients behaved this way, and apparently the usually don't since the proxy usually works :) Could be related to a Chrome update.

Anyway, I have made a quick fix and published 2.0.4-beta.1 It's in beta until I have put together a few unit tests to cover this case, but it didn't break any of the existing tests so I think it's safe for you to use. Looking forward for your feedback

[danbord]

Björn you nailed it!!! :D Everything is working fine with the beta version!!! Thanks a bunch!

[bjowes]

That's great to hear! Thanks for providing all the debugging data. I'll prepare a proper release within a few days.

Fixed in 2.0.4
