Class JAASMemoryLoginModule

  • All Implemented Interfaces:
    MBeanRegistration, LoginModule, Contained, JmxEnabled, Lifecycle, Realm

    public class JAASMemoryLoginModule
    extends MemoryRealm
    implements LoginModule

    Implementation of the JAAS LoginModule interface, primarily for use in testing JAASRealm. It utilizes an XML-format data file of username/password/role information identical to that supported by org.apache.catalina.realm.MemoryRealm.

    This class recognizes the following string-valued options, which are specified in the configuration file and passed to initialize(Subject, CallbackHandler, Map, Map) in the options argument:

    • pathname - Relative (to the pathname specified by the "catalina.base" system property) or absolute pathname to the XML file containing our user information, in the format supported by MemoryRealm. The default value matches the MemoryRealm default.
    • credentialHandlerClassName - The fully qualified class name of the CredentialHandler to use. If not specified, MessageDigestCredentialHandler will be used.
    • Any additional options will be used to identify and call setters on the CredentialHandler. For example, algorithm=SHA256 would result in a call to MessageDigestCredentialHandler.setAlgorithm(String) with a parameter of "SHA256"

    IMPLEMENTATION NOTE - This class implements Realm only to satisfy the calling requirements of the GenericPrincipal constructor. It does not actually perform the functionality required of a Realm implementation.
