/**
* A Configuration object is responsible for specifying which LoginModules
* should be used for a particular application, and in what order the
* LoginModules should be invoked.
*
* <p> A login configuration contains the following information.
* Note that this example only represents the default syntax for the
* {@code Configuration}. Subclass implementations of this class
* may implement alternative syntaxes and may retrieve the
* {@code Configuration} from any source such as files, databases,
* or servers.
*
* <pre>
* Name {
* ModuleClass Flag ModuleOptions;
* ModuleClass Flag ModuleOptions;
* ModuleClass Flag ModuleOptions;
* };
* Name {
* ModuleClass Flag ModuleOptions;
* ModuleClass Flag ModuleOptions;
* };
* other {
* ModuleClass Flag ModuleOptions;
* ModuleClass Flag ModuleOptions;
* };
* </pre>
*
* <p> Each entry in the {@code Configuration} is indexed via an
* application name, <i>Name</i>, and contains a list of
* LoginModules configured for that application. Each {@code LoginModule}
* is specified via its fully qualified class name.
* Authentication proceeds down the module list in the exact order specified.
* If an application does not have a specific entry,
* it defaults to the specific entry for "<i>other</i>".
*
* <p> The <i>Flag</i> value controls the overall behavior as authentication
* proceeds down the stack. The following represents a description of the
* valid values for <i>Flag</i> and their respective semantics:
*
* <pre>
* 1) Required - The {@code LoginModule} is required to succeed.
* If it succeeds or fails, authentication still continues
* to proceed down the {@code LoginModule} list.
*
* 2) Requisite - The {@code LoginModule} is required to succeed.
* If it succeeds, authentication continues down the
* {@code LoginModule} list. If it fails,
* control immediately returns to the application
* (authentication does not proceed down the
* {@code LoginModule} list).
*
* 3) Sufficient - The {@code LoginModule} is not required to
* succeed. If it does succeed, control immediately
* returns to the application (authentication does not
* proceed down the {@code LoginModule} list).
* If it fails, authentication continues down the
* {@code LoginModule} list.
*
* 4) Optional - The {@code LoginModule} is not required to
* succeed. If it succeeds or fails,
* authentication still continues to proceed down the
* {@code LoginModule} list.
* </pre>
*
* <p> The overall authentication succeeds only if all <i>Required</i> and
* <i>Requisite</i> LoginModules succeed. If a <i>Sufficient</i>
* {@code LoginModule} is configured and succeeds,
* then only the <i>Required</i> and <i>Requisite</i> LoginModules prior to
* that <i>Sufficient</i> {@code LoginModule} need to have succeeded for
* the overall authentication to succeed. If no <i>Required</i> or
* <i>Requisite</i> LoginModules are configured for an application,
* then at least one <i>Sufficient</i> or <i>Optional</i>
* {@code LoginModule} must succeed.
*
* <p> <i>ModuleOptions</i> is a space separated list of
* {@code LoginModule}-specific values which are passed directly to
* the underlying LoginModules. Options are defined by the
* {@code LoginModule} itself, and control the behavior within it.
* For example, a {@code LoginModule} may define options to support
* debugging/testing capabilities. The correct way to specify options in the
* {@code Configuration} is by using the following key-value pairing:
* <i>debug="true"</i>. The key and value should be separated by an
* 'equals' symbol, and the value should be surrounded by double quotes.
* If a String in the form, ${system.property}, occurs in the value,
* it will be expanded to the value of the system property.
* Note that there is no limit to the number of
* options a {@code LoginModule} may define.
*
* <p> The following represents an example {@code Configuration} entry
* based on the syntax above:
*
* <pre>
* Login {
* com.sun.security.auth.module.UnixLoginModule required;
* com.sun.security.auth.module.Krb5LoginModule optional
* useTicketCache="true"
* ticketCache="${user.home}${/}tickets";
* };
* </pre>
*
* <p> This {@code Configuration} specifies that an application named,
* "Login", requires users to first authenticate to the
* <i>com.sun.security.auth.module.UnixLoginModule</i>, which is
* required to succeed. Even if the <i>UnixLoginModule</i>
* authentication fails, the
* <i>com.sun.security.auth.module.Krb5LoginModule</i>
* still gets invoked. This helps hide the source of failure.
* Since the <i>Krb5LoginModule</i> is <i>Optional</i>, the overall
* authentication succeeds only if the <i>UnixLoginModule</i>
* (<i>Required</i>) succeeds.
*
* <p> Also note that the LoginModule-specific options,
* <i>useTicketCache="true"</i> and
* <i>ticketCache=${user.home}${/}tickets"</i>,
* are passed to the <i>Krb5LoginModule</i>.
* These options instruct the <i>Krb5LoginModule</i> to
* use the ticket cache at the specified location.
* The system properties, <i>user.home</i> and <i>/</i>
* (file.separator), are expanded to their respective values.
*
* <p> There is only one Configuration object installed in the runtime at any
* given time. A Configuration object can be installed by calling the
* {@code setConfiguration} method. The installed Configuration object
* can be obtained by calling the {@code getConfiguration} method.
*
* <p> If no Configuration object has been installed in the runtime, a call to
* {@code getConfiguration} installs an instance of the default
* Configuration implementation (a default subclass implementation of this
* abstract class).
* The default Configuration implementation can be changed by setting the value
* of the {@code login.configuration.provider} security property to the fully
* qualified name of the desired Configuration subclass implementation.
*
* <p> Application code can directly subclass Configuration to provide a custom
* implementation. In addition, an instance of a Configuration object can be
* constructed by invoking one of the {@code getInstance} factory methods
* with a standard type. The default policy type is "JavaLoginConfig".
* See the Configuration section in the <a href=
* "{@docRoot}/../technotes/guides/security/StandardNames.html#Configuration">
* Java Cryptography Architecture Standard Algorithm Name Documentation</a>
* for a list of standard Configuration types.
