Which file reads environment variables?

[kale1d0code]

I want to help fix the issue with AzureAD single sign-on
I have grepped for 'os.getenv' and got back way more then I bargained for.

which file is used to fetch settings from environment variables?
need to ensure SOCIAL_AUTH_AZUREAD_OAUTH2_KEY is read
