I’m using native app latest version 6.0.10 and getting 401 - Unauthorized: Access is denied due to invalid credentials while trying to test our WebAPI endpoints hosted in an IIS 7.5 server. For Authorization type, I have selected NTLM Authentication and supplied the Windows username and password.
Is the NTLM Authentication broken in version 6.0.10? If so how can I install a lower version that supports it?
That seems to be alright. I tested on an IIS server which is sending the exact same header and it’s working for me.
Can you try the same credentials by opening the URL in a browser window? Does that work?
Also, if possible share following information (either here or mail us at [email protected]):
num of requests that you see in postman-console (3 or 4)
complete raw log of each request (see below example screenshot)
Did this issue ever get resolved? I’m having similar NTLM issues but it seems these threads usually go dead without solution. Any info you can provide would be most helpful.
I am having the same issue with a much newer version of Postman.
Version 7.26.1
win32 10.0.18363 / x64
My request works fine in the browser (Edge + Chrome) and works without issue in Insomnia. I don’t really want to switch to Insomnia but at least it seems to be working using that tool.
