Interface AuthInitialize

All Superinterfaces:

CacheCallback

public interface AuthInitialize
extends CacheCallback

Specifies the mechanism to obtain credentials for a client or peer. It is mandatory for clients and peers when running in secure mode and an Authenticator has been configured on the server/locator side respectively. Implementations should register name of the static creation function (that returns an object of the class) as the security-peer-auth-init system property on peers and as the security-client-auth-init system property on clients.

Since:

5.5

Method Detail

init

void init(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:

systemLogger - LogWriter for system logs

securityLogger - LogWriter for security logs

Throws:

AuthenticationFailedException - if some exception occurs during the initialization

getCredentials

Properties getCredentials(Properties securityProps,
                        DistributedMember server,
                        boolean isPeer)
                          throws AuthenticationFailedException

Initialize with the given set of security properties and return the credentials for the peer/client as properties. This method can modify the given set of properties. For example it may invoke external agents or even interact with the user. Normally it is expected that implementations will filter out security-* properties that are needed for credentials and return only those.

Parameters:

securityProps - the security properties obtained using a call to DistributedSystem.getSecurityProperties() that will be used for obtaining the credentials

server - the DistributedMember object of the server/group-coordinator to which connection is being attempted

isPeer - true when this is invoked for peer initialization and false when invoked for client initialization

Returns:

the credentials to be used for the given server

Throws:

AuthenticationFailedException - in case of failure to obtain the credentials
