Interface SaslServerFactory


public interface SaslServerFactory

An interface for creating instances of SaslServer. 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 server, which will use the Sasl static methods instead. However, a particular environment may provide and install a new or different SaslServerFactory.

Since:
1.5

Method Summary
 SaslServer createSaslServer(String mechanism, String protocol, String serverName, Map<String,?> props, CallbackHandler cbh)
          Creates a SaslServer using the parameters supplied.
 String[] getMechanismNames(Map<String,?> props)
          Returns an array of names of mechanisms that match the specified mechanism selection policies.
 

Method Detail

createSaslServer

SaslServer createSaslServer(String mechanism,
                            String protocol,
                            String serverName,
                            Map<String,?> props,
                            CallbackHandler cbh)
                            throws SaslException
Creates a SaslServer using the parameters supplied. It returns null if no SaslServer can be created using the parameters supplied. Throws SaslException if it cannot create a SaslServer because of an error.

Parameters:
mechanism - The non-null IANA-registered name of a SASL mechanism. (e.g. "GSSAPI", "CRAM-MD5").
protocol - The non-null string name of the protocol for which the authentication is being performed (e.g., "ldap").
serverName - The non-null fully qualified host name of the server to authenticate to.
props - 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.
cbh - 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.
Returns:
A possibly null SaslServer created using the parameters supplied. If null, this factory cannot produce a SaslServer using the parameters supplied.
Throws:
SaslException - If cannot create a SaslServer because of an error.

getMechanismNames

String[] getMechanismNames(Map<String,?> props)
Returns an array of names of mechanisms that match the specified mechanism selection policies.

Parameters:
props - 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.
Returns:
A non-null array containing a IANA-registered SASL mechanism names.
