Hi Experts,
We have a customer who is setting up OIDC SSO login (Azure AD) on a on-premise environment which have a firewall which restricts access to the internet.
Due to this they are getting 500 status code error on webclient and smart client (OIDC123). The same credentials used on another internet accessible environment it is working as expected.
They are asking which URLs they need to whitelist in order to get OIDC working.
So far they’ve whitelisted following URLs (ref)
*.login.microsoftonline.com
*.aadcdn.msftauth.net
*.aadcdn.msftauthimages.net
*.aadcdn.msauthimages.net
*.logincdn.msftauth.net
*.login.live.com
*.msauth.net
*.aadcdn.microsoftonline-p.com
