JAAS config for Oauthbearer configuration

[Shawcs]

Hello, when I try to configure the schema registry to communicate with an oauth secured kafka cluster I got: Login module control flag not specified in JAAS config when I run /etc/confluent/docker/launch inside my docker image

My setup is the following:

• Kafka cluster on premise (not a confluent one)
• Authentication provider is a Windows ADFS (tested and working with spring/quarkus kafka clients)
• All running inside docker containers

I'm using a configuration looking like this for the registry inside my schema-registry.properties file:

kafkastore.sasl.jaas.config= 'org.apache.kafka.common.security.oauthbearer.OAuthBearerLoginModule required oauth.client.id="registry-client" oauth.client.secret="MY_SECRET" oauth.token.endpoint.uri="https://login.dev.net/adfs/oauth2/token" ;'
kafkastore.security.protocol=SASL_SSL
kafkastore.sasl.mechanism=OAUTHBEARER

any idea what config I could miss or if it's a licence problem ?

Try it without the single quotation marks.
