Is there a way to pass Windows Authentication with postman?
I have added this in header but still 401 Unauthorized.
Authorization: NTLM TkFcYWRtaW46dGVzdA==
As suggested by this link. I've encrypted as Unicode (UTF-16, little-endian) but of no use.
Any Ideas?
I got this working by running Fiddler first.
Run Fiddler (I'm using 4.6.2.3)
Fiddler Menu: Rule -> Automatically Authenticate = true
Postman: Check that Authorization type = No Auth
Browse api.
you can use the the NTLM authorization exist in the Authorization tab same as this photo
I don't think there is a way to do that. But, you are not alone in wanting it...

[EDIT]
As of the addition of this edit, Postman has NTLM Authentication in beta in their most recent release.
https://www.getpostman.com/docs/v6/postman/sending_api_requests/authorization
I suggest using insomnia. It's free and you can see the documentation on how to add NTLM Auth here: https://insomnia.rest/documentation/authentication/
NTLM authentication does work with the Chrome plugin version of Postman, as the built-in Chrome NTLM authentication can be used with the plugin. However, plugins are no longer supported by Chrome, so this version can no longer be installed and used.
The current app version of Postman (both the Chrome app and native app versions) does not support NTLM authentication.
This was added to the Postman application in 5.3.0. However, this support was broken in 5.4.1 and remained broken until 7.14.0 per Postman App issue #4355. Updating the app to a newer version of Postman should therefore allow using NTLM authentication.
Note that Postman currently only supports NTLMv1 authentication but not NTLMv2 per Postman App issue #8038.
I will improve upon Hala's answer as it is problematic due to storing credentials in the request and these might get persisted in a shared repository if one is used.
Clear credentials once a request has been successfully issued
One way is to enter the credentials - username, password and domain - make the request and remove them. Subsequent requests will work, probably due to using the same NTLM authentication header, as Postman will add a temporary Authorization header (blurred) that has a value like the following: NTLM some_base64_content
Use environment variables (or better global ones as suggested by SSS) to store sensitive data
Define an environment to use and configure it similar to this:
Use configured environment variables in the request:
You can also change internet options and set Logon to:
Automatic logon with current user name and password
taken from:
https://sysadminspot.com/windows/google-chrome-and-ntlm-auto-logon-using-windows-authentication/
if the website uses https you can add it to Trusted Sites and set it there, otherwise you can add it to local intranet sites and set Custom level... there.
Open internet options:
Click Custom level... and scroll to bottom:
Postman now does NTLM on their desktop apps only.
If you develop your API in C# you can use the following on your Base Controller
#if !DEBUG
[Authorize]
#endif

I made a self-hosted web service in C# (but I don't think the language and framework matter here). The service requires NTLM authentication. When I test the service from Chrome everything works. If I test it from Postman then a certain check fails in the service. In my ApiController I call ((WindowsIdentity)User.Identity).Owner.IsAccountSid() and this method returns false when web calls are made from Postman. The owner's SID is S-1-5-32-544 (Administrators group), which is not an account.
In Postman I did set the username and password, as suggested in another answer. If I change the password, I get 401 Unauthorized, so this tells me I configured Postman correctly. But it doesn't work for me.
Is there a way to make Postman behave more like Chrome (where both direct link and call from JavaScript work correctly)?
Is there a way to disable the X-Frame-Options header in the WSO2IS responses? We need to integrate one application within another with the use of an iframe. Both applications are using WSO2IS for authentication though the one in the iframe will redirect to authenticate with OpenID Connect but it should return back immediately since the user has been authenticated by the parent application. Now as it is, I get X-Frame-Options: DENY headers and since the WSO2IS is located in a different domain than the application. Any suggestions?
After a little thought and since there is no answer yet, I believe I can answer my own question. Since it seems that every SSO system out there will serve the X-Frame-Options header with a DENY value, the only solution would be to pass the OpenID Connect Code from the parent application to the iframe child application as a parameter. In that way, the redirection step is not needed and thus the nested/child/whatever application can make the requests for the token and user info. I don't know if this is a nice way to do it, but it seems the only way that will work with WSO2IS or any other OpenID Connect based SSO system.
I'm experiencing the same issue as the one mentioned here, for which there was no conclusive answer: Asp.Net Owin authorized request works in Incognito mode but not "normal" Chrome
I am unable to comment on that question as I do not have the reputation to allow but was going to ask whether it is something to do with the fact that my project includes both Web Forms and Web API and there is a conflict going on with the authorization cookie.
Has anyone else come across this issue?
Thanks
For the benefit of anyone else with the same issue:
It was indeed due to forms authentication being enabled at the same time as OWIN bearer tokens.
If you are logged in via forms authentication, then try to call a web api end-point in the same browser, it uses the cookie information which gets recognized by Web Api authorization.
In incognito, there is no such cookie so behaves as expected.
I'm using SoapUI 5.2.1 and accessing a IIS hosted web service on my domain. The web service has windows authentication enabled.
When I browse to the wsdl using internet explorer, it asks for my credentials, then shows the wsdl.
When I do the exact same with soapui, it prompts for my details, then fails and when I check the http log it sayus 'unauthorised: access is denied due to invalid credentials'.
But I'm entering it correctly, I've even tried various permutations of domain\username, username, leaving the domain text box blank or entering it there.
Any ideas?
I needed to provide a lot more info than would fit into a comment...
The other setting that I was referring to is detailed here : https://www.soapui.org/soap-and-wsdl/authenticating-soap-requests.html. If you are sure its windows credentials authentication, then use the NTLM setting. You may have to restart for the settings to take effect.
"Domain – add this for NTLM authentication challenges. If you are authenticating NTLM, make sure to note the following in your configurations:
File > Preferences > HTTP Settings tab > uncheck Authenticate Preemptively preference
for NTLM v2 provide your username as "DOMAIN\USERNAME" or at least as "\USERNAME""
If you still have issues, you can use BURP suite or Fiddler or similar proxy tools for proxy setup. BURP is an extensive security testing tool and may even be an overkill. Fiddler is a proxy. Check out these two links:

I'm trying to use WSO2 API Manager 1.10.0 on an existent micro-services project with REST APIs following WSO2 tutorial.
I have installed it on my computer as well as a copy of my application and configured AM to manage requests (GET, POST and DELETE) to my resource but I always obtain a "Response code 0" with Response Header
{
"error": "no response from server"
}
Trying to contact my application using Advanced REST Client I obtain 200 with the correct result.
My APIs use a token inside the header to authenticate the user passed so I have implemented a dummy API without authentication but I still have the same issue.
I have tried also the Cloud version with our test server but still obtaining the same result.
I found this guide http://wso2.com/blogs/cloud/video-setting-up-custom-url-for-api-store-and-gateway/ but I don't know if this can be a solution for the problem in localhost.
Setting up the custom url in WSO2 API Cloud wont help. Thats there for a different purpose. There are two things you can do.
If you are interested in going ahead with the cloud version, you can get help from them. You can send a support request and the cloud team will help.
You can troubleshoot your local instance. When doing so, first, try to invoke your api via curl and see whether it gets a response. Sometime, your api can work fine, but due to some reasons, the result might not reach the api console.
If the curl works fine or not, you can check the logs to see whether there are any errors printed. Some more questions:
Is your backend service exposed via http or https?
If it is https, then if its certificate is not a CA signed one, API Manager will fail during the handshake. If so, you will have to add the cert to api managers client-truststore.jks
In the cloud scenario, your backend should be accessible from internet and the certificate story is valid for cloud too.
Are you trying to access the api using swagger console (or any web application). There are couple of reasons you could encounter this issue. one could be certificate not installed in the browser.
If this happens you should see some error log in the api manager console (something related to CA not found). for that first you can copy the backend url (swagger console shows the url it used to send the request) and paste it on a new browser window and install the certificate to the browser.
also you can get an idea about the issue by using a tool like firebug and check the request. (it will show the error for not connecting the AM)
Finally I have found the issue: the API Manager does not accept plain text response, responding using a JSON solves the problem.
Using other mediatype such as XML or TEXT/HTML it reports 406, with text plain it returns Error 0.
