wso2 bam2.4 connect to external cassandra failed by .AuthenticationException - wso2

Question

I think I have followed all the examples what I can find,
and I am working on bam2.4.1, the apache cassandra is 2.1.2.
I have configured casandra to disable security by setting cassandra.yaml
authenticator: AllowAllAuthenticator
authorizer: AllowAllAuthorizer
Then I follow bam2.4.1 document to connect to external cassandra, then start wso2 bam by
wso2server.bat -Ddisable.cassandra.server.startup=true
All most everything works except authentication
