/**
* This {@link LoginModule} performs file-based authentication.
*
* <p> A supplied username and password is verified against the
* corresponding user credentials stored in a designated password file.
* If successful then a new {@link JMXPrincipal} is created with the
* user's name and it is associated with the current {@link Subject}.
* Such principals may be identified and granted management privileges in
* the access control file for JMX remote management or in a Java security
* policy.
*
* <p> The password file comprises a list of key-value pairs as specified in
* {@link Properties}. The key represents a user's name and the value is its
* associated cleartext password. By default, the following password file is
* used:
* <pre>
* ${java.home}/lib/management/jmxremote.password
* </pre>
* A different password file can be specified via the <code>passwordFile</code>
* configuration option.
*
* <p> This module recognizes the following <code>Configuration</code> options:
* <dl>
* <dt> <code>passwordFile</code> </dt>
* <dd> the path to an alternative password file. It is used instead of
* the default password file.</dd>
*
* <dt> <code>useFirstPass</code> </dt>
* <dd> if <code>true</code>, this module retrieves the username and password
* from the module's shared state, using "javax.security.auth.login.name"
* and "javax.security.auth.login.password" as the respective keys. The
* retrieved values are used for authentication. If authentication fails,
* no attempt for a retry is made, and the failure is reported back to
* the calling application.</dd>
*
* <dt> <code>tryFirstPass</code> </dt>
* <dd> if <code>true</code>, this module retrieves the username and password
* from the module's shared state, using "javax.security.auth.login.name"
* and "javax.security.auth.login.password" as the respective keys. The
* retrieved values are used for authentication. If authentication fails,
* the module uses the CallbackHandler to retrieve a new username and
* password, and another attempt to authenticate is made. If the
* authentication fails, the failure is reported back to the calling
* application.</dd>
*
* <dt> <code>storePass</code> </dt>
* <dd> if <code>true</code>, this module stores the username and password
* obtained from the CallbackHandler in the module's shared state, using
* "javax.security.auth.login.name" and
* "javax.security.auth.login.password" as the respective keys. This is
* not performed if existing values already exist for the username and
* password in the shared state, or if authentication fails.</dd>
*
* <dt> <code>clearPass</code> </dt>

*
* <p>A typical use of this class is to insert it between a connector server
* such as the RMI connector and the MBeanServer with which the connector
* is associated. Requests from the connector client can then be filtered
* and those operations that are not allowed, or not allowed in a particular
* context, can be rejected by throwing a <code>SecurityException</code>
* in the corresponding <code>check*</code> method.</p>
*
* <p>This is an abstract class, because in its implementation none of
* the checking methods does anything. To be useful, it must be
* subclassed and at least one of the checking methods overridden to
* do some checking. Some or all of the MBeanServer methods may also
* be overridden, for instance if the default checking behavior is
* inappropriate.</p>
*
* <p>If there is no SecurityManager, then the access controller will refuse
* to create an MBean that is a ClassLoader, which includes MLets, or to
* execute the method addURL on an MBean that is an MLet. This prevents
* people from opening security holes unintentionally. Otherwise, it
* would not be obvious that granting write access grants the ability to
* download and execute arbitrary code in the target MBean server. Advanced
* users who do want the ability to use MLets are presumably advanced enough
* to handle policy files and security managers.</p>
