/**
* This class is for authentication permissions. An {@code AuthPermission}
* contains a name (also referred to as a "target name") but no actions
* list; you either have the named permission or you don't.
*
* The target name is the name of a security configuration parameter
* (see below). Currently the {@code AuthPermission} object is used to
* guard access to the {@link Subject},
* {@link javax.security.auth.login.LoginContext}, and
* {@link javax.security.auth.login.Configuration} objects.
*
*
The standard target names for an Authentication Permission are:
*
*
* doAs - allow the caller to invoke the
* {@code Subject.doAs} methods.
*
* doAsPrivileged - allow the caller to invoke the
* {@code Subject.doAsPrivileged} methods.
*
* getSubject - allow for the retrieval of the
* Subject(s) associated with the
* current Thread.
*
* getSubjectFromDomainCombiner - allow for the retrieval of the
* Subject associated with the
* a {@code SubjectDomainCombiner}.
*
* setReadOnly - allow the caller to set a Subject
* to be read-only.
*
* modifyPrincipals - allow the caller to modify the {@code Set}
* of Principals associated with a
* {@code Subject}
*
* modifyPublicCredentials - allow the caller to modify the
* {@code Set} of public credentials
* associated with a {@code Subject}
*
* modifyPrivateCredentials - allow the caller to modify the
* {@code Set} of private credentials
* associated with a {@code Subject}
*
* refreshCredential - allow code to invoke the {@code refresh}
* method on a credential which implements
* the {@code Refreshable} interface.
*
* destroyCredential - allow code to invoke the {@code destroy}
* method on a credential {@code object}
* which implements the {@code Destroyable}
* interface.
*
* createLoginContext.{name} - allow code to instantiate a
* {@code LoginContext} with the
* specified {@code name}. {@code name}
* is used as the index into the installed login
* {@code Configuration}
* (that returned by
* {@code Configuration.getConfiguration()}).
* name can be wildcarded (set to '*')
* to allow for any name.
*
* getLoginConfiguration - allow for the retrieval of the system-wide
* login Configuration.
*
* createLoginConfiguration.{type} - allow code to obtain a Configuration
* object via
* {@code Configuration.getInstance}.
*
* setLoginConfiguration - allow for the setting of the system-wide
* login Configuration.
*
* refreshLoginConfiguration - allow for the refreshing of the system-wide
* login Configuration.
*
*
* Please note that granting this permission with the "modifyPrincipals",
* "modifyPublicCredentials" or "modifyPrivateCredentials" target allows
* a JAAS login module to populate principal or credential objects into
* the Subject. Although reading information inside the private credentials
* set requires a {@link PrivateCredentialPermission} of the credential type to
* be granted, reading information inside the principals set and the public
* credentials set requires no additional permission. These objects can contain
* potentially sensitive information. For example, login modules that read
* local user information or perform a Kerberos login are able to add
* potentially sensitive information such as user ids, groups and domain names
* to the principals set.
*
*
The following target name has been deprecated in favor of
* {@code createLoginContext.{name}}.
*
*
* createLoginContext - allow code to instantiate a
* {@code LoginContext}.
*
*
* @implNote
* Implementations may define additional target names, but should use naming
* conventions such as reverse domain name notation to avoid name clashes.
* @since 1.4
