I am not sure what kind of authentication needs to be passed here.

@smitpatel Yes, this is an authorization thing that everyone runs into -- you have to do on the build to make it accept forks (in AzDO). I don't remember what it is off the top of my head (been a while since I've seen it) but I'll track it down for you as soon as I can.

[jonfortescue]

Ah, I found it. Instructions here: https://docs.microsoft.com/en-us/azure/devops/pipelines/repos/github?view=azure-devops&tabs=yaml#validate-contributions-from-forks

[jonfortescue]

Ensure that you don't check "make secrets available," however.

[smitpatel]

This is current settings which allows PR from forks still it has failed. Anymore checkbox I have to tick?

[jonfortescue]

Talked to Smit offline and this should be resolved; I was mistaken on checking "make secrets available." @smitpatel please close this after you've confirmed it's working!

[smitpatel]

Verified working.
