Can no longer authenticate to NPrinting API

[jjb427]

Hello, I have been using the NPrinting API, but suddenly on 7/31 I've started receiving authentication failures (401) when making calls to the API. I'm using the /login/ntlm endpoint to connect. Using postman, yesterday I was able to successfully authenticate once and proceed to make additional calls to the API, but once I disconnected it went back to the authentication failures. I have tried via multiple admin accounts and have used a python script as well as postman in attempts to connect.

Hello there.

Something must have changed.

Check this article very carefully to help you determine what may have changed.

Hi @jjb427 

Can you share your raw cookie string... feel free to scramble some of it but make sure you keep the key words where they need to be so we can gather what layout you need and how your cookie needs to be extracted. 

I had to change recently the way I extract cookie for myself.

cheers

Thanks! The issue was that the AD domain admin account's password had expired.
