Interface Authenticator

All Superinterfaces:

CacheCallback

public interface Authenticator
extends CacheCallback

Specifies the mechanism to verify credentials for a client or peer. Implementations should register name of the static creation function as the security-peer-authenticator system property with all the locators in the distributed system for peer authentication, and as security-client-authenticator for client authentication. For P2P an object is initialized on the group coordinator for each member during the DistributedSystem.connect(Properties) call of a new member. For client-server, an object of this class is created for each connection during the client-server handshake. The static creation function should have the following signature: public static Authenticator [method-name](); i.e. it should be a zero argument function.

Since:

5.5

init

void init(Properties securityProps,
          LogWriter systemLogger,
          LogWriter securityLogger)
          throws AuthenticationFailedException

Initialize the callback for a client/peer. This is invoked when a new connection from a client/peer is created with the host.

Parameters:

securityProps - the security properties obtained using a call to DistributedSystem.getSecurityProperties()

systemLogger - LogWriter for system logs

securityLogger - LogWriter for security logs

Throws:

AuthenticationFailedException - if some exception occurs during the initialization

authenticate

Principal authenticate(Properties props,
                       DistributedMember member)
                       throws AuthenticationFailedException

Verify the credentials provided in the properties for the client/peer as specified in member ID and returns the principal associated with the client/peer.

Parameters:

props - the credentials of the client/peer as a set of property key/values

member - the DistributedMember object of the connecting client/peer member. NULL when invoked locally on the member initiating the authentication request.

Returns:

the principal for the client/peer when authentication succeeded

Throws:

AuthenticationFailedException - If the authentication of the client/peer fails.
