I am facing issue while connecting IBM app connect to kafka through SASL connection using OAUTHBEARER. Below are the property provided by the kafka team.
ssl.truststore.location=/abc/config/kafka/ssl/client.truststore.jks
ssl.truststore.password=changeme
sasl.server.callback.handler.class=aero.sita.bordermanagement.eventbus.authentication.ClientAuthenticateCallbackHandler
sasl.mechanism=OAUTHBEARER
sasl.jaas.config=org.apache.kafka.common.security.oauthbearer.OAuthBearerLoginModule required sasl.oauthbearer.token.endpoint.url="https://testserver:443/openam/oauth2/realms/root/realms/ptd-portal-security/access_token" oauth.token.grant.type="password" client.id="servicesSecurityClient" client.secret="abc@1234" username="SITRISKASSESSMENTSYSTEMUSER" password="abc@1234";
I am getting below error,
Caused by: javax.security.auth.login.LoginException: An internal error occurred while retrieving token from callback handler
