createSaslServer

public SaslServer createSaslServer(java.lang.String mechanism,
                                   java.lang.String protocol,
                                   java.lang.String serverName,
                                   java.util.Map props,
                                   CallbackHandler cbh)
                            throws SaslException

Description copied from interface: SaslServerFactory

Creates a SaslServer instance using the parameters supplied. It returns null if no SaslServer instance can be created using the parameters supplied. Throws SaslException if it cannot create a SaslServer because of an error.

Specified by:

createSaslServer in interface SaslServerFactory

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 is returned, it means that this factory cannot produce a SaslServer using the parameters supplied.

Throws:

SaslException - if a SaslServer instance cannot be created because of an error.

getMechanismNames

public java.lang.String[] getMechanismNames(java.util.Map props)

Description copied from interface: SaslServerFactory

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

Specified by:

getMechanismNames in interface SaslServerFactory

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 IANA-registered SASL mechanism names.
