Class PasswordAuthenticator

java.lang.Object

org.apache.cassandra.auth.PasswordAuthenticator

All Implemented Interfaces:

IAuthenticator

public class PasswordAuthenticator
extends java.lang.Object
implements IAuthenticator

PasswordAuthenticator is an IAuthenticator implementation that keeps credentials (rolenames and bcrypt-hashed passwords) internally in C* - in system_auth.roles CQL3 table. Since 2.2, the management of roles (creation, modification, querying etc is the responsibility of IRoleManager. Use of PasswordAuthenticator requires the use of CassandraRoleManager for storage and retrieval of encrypted passwords.

public PasswordAuthenticator()

Method Detail

requireAuthentication

public boolean requireAuthentication()

Description copied from interface: IAuthenticator

Whether or not the authenticator requires explicit login. If false will instantiate user with AuthenticatedUser.ANONYMOUS_USER.

Specified by:

requireAuthentication in interface IAuthenticator

protectedResources

public java.util.Set<DataResource> protectedResources()

Description copied from interface: IAuthenticator

Set of resources that should be made inaccessible to users and only accessible internally.

Specified by:

protectedResources in interface IAuthenticator

Returns:

Keyspaces, column families that will be unmodifiable by users; other resources.

validateConfiguration

public void validateConfiguration()
                           throws ConfigurationException

Description copied from interface: IAuthenticator

Validates configuration of IAuthenticator implementation (if configurable).

Specified by:

validateConfiguration in interface IAuthenticator

Throws:

ConfigurationException - when there is a configuration error.

setup

public void setup()

Description copied from interface: IAuthenticator

Setup is called once upon system startup to initialize the IAuthenticator. For example, use this method to create any required keyspaces/column families.

Specified by:

setup in interface IAuthenticator

legacyAuthenticate

public AuthenticatedUser legacyAuthenticate(java.util.Map<java.lang.String,java.lang.String> credentials)
                                     throws AuthenticationException

Description copied from interface: IAuthenticator

For implementations which support the Thrift login method that accepts arbitrary key/value pairs containing credentials data. Also used by CQL native protocol v1, in which username and password are sent from client to server in a CredentialsMessage Implementations where support for Thrift and CQL protocol v1 is not required should make this an unsupported operation. Should never return null - always throw AuthenticationException instead. Returning AuthenticatedUser.ANONYMOUS_USER is an option as well if authentication is not required.

Specified by:

legacyAuthenticate in interface IAuthenticator

Parameters:

credentials - implementation specific key/value pairs

Returns:

non-null representation of the authenticated subject

Throws:

AuthenticationException

newSaslNegotiator

public IAuthenticator.SaslNegotiator newSaslNegotiator()

Description copied from interface: IAuthenticator

Provide a SASL handler to perform authentication for an single connection. SASL is a stateful protocol, so a new instance must be used for each authentication attempt.

Specified by:

newSaslNegotiator in interface IAuthenticator

Returns:

org.apache.cassandra.auth.IAuthenticator.SaslNegotiator implementation (see PasswordAuthenticator.PlainTextSaslAuthenticator)
