Currently I am developing Symfony application where I have multiple login form. For the login form I created the firewall and also created custom authenticator. New created custom authenticator added into the services.yaml file as well.
Authenticator working perfectly when added to the main firewall but it is not working with the oauth_login firewall.
New authenticator file is manually created.
When ever I try to login with oauth_login form, I am not able to login and also OLoginFormAuthenticator is not called.
Edit:
Following changes worked for me
