As of release 1.0, the SimpleAuthenticator and SimpleAuthority classes have been moved to the example directory of the Apache Cassandra project repository. They are no longer available in the packaged and binary distributions. They are only examples and do not provide actual security in their current state. DataStax does not officially support them and do not recommend their use.
Using authentication and authorization requires configuration changes in cassandra.yaml and two additional files: one for assigning users and their permissions to keyspaces and column families, and the other for assigning passwords to those users. These files are named access.properties and passwd.properties, respectively, and are located in the examples directory of the Apache Cassandra project repository. To test simple authentication, you can move these files to the conf directory.
This file contains entries in the format KEYSPACE[.COLUMNFAMILY].PERMISSION=USERS where
KEYSPACE is the keyspace name.
COLUMNFAMILY is the column family name.
PERMISSION is one of <ro> or <rw> for read-only or read-write respectively.
USERS is a comma delimited list of users from passwd.properties.
For example, to control access to Keyspace1 and give jsmith and Elvis read-only permissions while allowing dilbert full read-write access to add and remove column families, you would create the following entries:
This file contains name/value pairs in which the names match
users defined in access.properties and the values are user passwords.
Passwords are in clear text unless the
passwd.mode=MD5 system property is provided.
