public Interface SaslClientFactory

Known Direct Implementers
com.sun.security.sasl.ClientFactoryImpl, com.sun.security.sasl.digest.FactoryImpl, com.sun.security.sasl.ntlm.FactoryImpl
Imports
java.util.Map, javax.security.auth.callback.CallbackHandler

An interface for creating instances of SaslClient. A class that implements this interface must be thread-safe and handle multiple simultaneous requests. It must also have a public constructor that accepts no argument.

This interface is not normally accessed directly by a client, which will use the Sasl static methods instead. However, a particular environment may provide and install a new or different SaslClientFactory.

Method Summary

Modifier and TypeMethod and Description
public SaslClient

Returns:

A possibly null SaslClient created using the parameters supplied. If null, this factory cannot produce a SaslClient using the parameters supplied.
createSaslClient
(String[]
The non-null list of mechanism names to try. Each is the IANA-registered name of a SASL mechanism. (e.g. "GSSAPI", "CRAM-MD5").
mechanisms
,
String
The possibly null protocol-dependent identification to be used for authorization. If null or empty, the server derives an authorization ID from the client's authentication credentials. When the SASL authentication completes successfully, the specified entity is granted access.
authorizationId
,
String
The non-null string name of the protocol for which the authentication is being performed (e.g., "ldap").
protocol
,
String
The non-null fully qualified host name of the server to authenticate to.
serverName
,
Map<String, ?>
The possibly null set of properties used to select the SASL mechanism and to configure the authentication exchange of the selected mechanism. See the Sasl class for a list of standard properties. Other, possibly mechanism-specific, properties can be included. Properties not relevant to the selected mechanism are ignored, including any map entries with non-String keys.
props
,
CallbackHandler
The possibly null callback handler to used by the SASL mechanisms to get further information from the application/library to complete the authentication. For example, a SASL mechanism might require the authentication ID, password and realm from the caller. The authentication ID is requested by using a NameCallback. The password is requested by using a PasswordCallback. The realm is requested by using a RealmChoiceCallback if there is a list of realms to choose from, and by using a RealmCallback if the realm must be entered.
cbh
)

Creates a SaslClient using the parameters supplied.

public String[]

Returns:

A non-null array containing a IANA-registered SASL mechanism names.
getMechanismNames
(Map<String, ?>
The possibly null set of properties used to specify the security policy of the SASL mechanisms. For example, if props contains the Sasl.POLICY_NOPLAINTEXT property with the value "true", then the factory must not return any SASL mechanisms that are susceptible to simple plain passive attacks. See the Sasl class for a complete list of policy properties. Non-policy related properties, if present in props, are ignored, including any map entries with non-String keys.
props
)

Returns an array of names of mechanisms that match the specified mechanism selection policies.

Method Detail

public SaslClient createSaslClient(String[] mechanisms, String authorizationId, String protocol, String serverName, Map<String, ?> props, CallbackHandler cbh) throws SaslException

Creates a SaslClient using the parameters supplied.

Parameters
mechanisms:String[]

The non-null list of mechanism names to try. Each is the IANA-registered name of a SASL mechanism. (e.g. "GSSAPI", "CRAM-MD5").

authorizationId:String

The possibly null protocol-dependent identification to be used for authorization. If null or empty, the server derives an authorization ID from the client's authentication credentials. When the SASL authentication completes successfully, the specified entity is granted access.

protocol:String

The non-null string name of the protocol for which the authentication is being performed (e.g., "ldap").

serverName:String

The non-null fully qualified host name of the server to authenticate to.

props:Map<String, ?>

For example, a SASL mechanism might require the authentication ID, password and realm from the caller. The authentication ID is requested by using a NameCallback. The password is requested by using a PasswordCallback. The realm is requested by using a RealmChoiceCallback if there is a list of realms to choose from, and by using a RealmCallback if the realm must be entered.

Returns:SaslClient

A possibly null SaslClient created using the parameters supplied. If null, this factory cannot produce a SaslClient using the parameters supplied.

Exceptions
SaslException:
If cannot create a SaslClient because of an error.
getMechanismNamesback to summary
public String[] getMechanismNames(Map<String, ?> props)

Returns an array of names of mechanisms that match the specified mechanism selection policies.

Parameters
props:Map<String, ?>

The possibly null set of properties used to specify the security policy of the SASL mechanisms. For example, if props contains the Sasl.POLICY_NOPLAINTEXT property with the value "true", then the factory must not return any SASL mechanisms that are susceptible to simple plain passive attacks. See the Sasl class for a complete list of policy properties. Non-policy related properties, if present in props, are ignored, including any map entries with non-String keys.

Returns:String[]

A non-null array containing a IANA-registered SASL mechanism names.
