Can we add custom headers to the token endpoint?
`curl --location --request POST 'https://localhost:8081/auth/realms/global/protocol/openid-connect/token' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'client_id=login' \
--data-urlencode 'username=balabla@bla.com' \
--data-urlencode 'password=balbabsfeds@123' `
We are using userfederation with custom logic to determine whether the credentials are authentic. We’ve implemented the authentication spi shown below. implements UserStorageProvider, UserLookupProvider, CredentialInputValidator, CredentialInputUpdater, UserRegistrationProvider
