Method Detail

createSaslServer

  1. public SaslServer createSaslServer( java.lang.String mech,
  2. java.lang.String protocol,
  3. java.lang.String serverName,
  4. java.util.Map<java.lang.String,?> props,
  5. javax.security.auth.callback.CallbackHandler cbh)
  6. throws SaslException
Description copied from interface: SaslServerFactory
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.
Specified by:
Parameters:
mech - 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

  1. public java.lang.String[] getMechanismNames( java.util.Map<java.lang.String,?> props)
Description copied from interface: SaslServerFactory
Returns an array of names of mechanisms that match the specified mechanism selection policies.
Specified by:
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.
