I tried to configure Authentication using HTTP basic according to https://pulsar.apache.org/docs/security-basic-auth/ but unfortunately it didn't work. There is a Failed to load an authentication provider entry in the logs. Someone knows what the problem could be.
OS => Ubuntu 20.04
Pulsar Version => 2.10.1
authenticationEnabled=true
authenticationProviders=org.apache.pulsar.broker.authentication.AuthenticationProviderBasic
basicAuthConf=file:///opt/apache-pulsar-2.10.1/auth/.htpasswd
basicAuthConf=data:;base64,#MY PASS
basicAuthConf=#MY PASS
brokerClientAuthenticationPlugin=org.apache.pulsar.client.impl.auth.AuthenticationBasic
brokerClientAuthenticationParameters={"userId":"superuser","password":"admin"}
authenticateOriginalAuthData=true
