[keycloak-user] Developing with keycloak-adapter without an OAuth Server

Hi all, I've been developing a J2EE application utilizing the keycload-wildfly adapter to connect to a 3rd party OAuth server. Now the customer who I'm developing this application for also has another vendor creating an OAuth server. After almost 2 years of developing they have now restricted access to the OAuth server and I can no longer access it from my local environment. They expect me to push my code up to their remote development server to test changes. What is the best way I can go from here? I have tons of code utilizing the attributes in a token, and I don't understand fully how to customize the keycloak-adapter to skip certain functions in a development environment. I was told my local environment shouldn't need to access the OAuth server yet I don't understand how to bypass/fake certain functions. For example, all of my .xhtml pages are secured in the .WAR's web.xml using <login-config> <auth-method>KEYCLOAK</auth-method> </login-config> that is what triggers the redirect to OAuth (if a token isn't active/valid.) How can I basically "skip" this authentication check in a local environment? I have stood up my own keycloak server which I can authenticate with, but the customer's OAuth server vendor has done custom modifications to their keycloak server. For example, they have added extra fields where first/last name are, where on regular keycloak that would be a user-attribute map. TLDR; Is there anything in the keycloak-adapter that would skip authentication in a development environment. Is there a way to create a fake base64 token? Or during login of my application (where I extract user attributes and their custom attributes) should I make it so it works for either OAuth server? Thank you for any help.
