Java in a Nutshell, 5th Edition [Electronic resources] نسخه متنی

This
inner

class defines a
"control flag"
type
and four specific instances of that type. The constants defined by
this class specify whether a login module is required or optional,
and have the following meanings:

REQUIRED

Authentication by this module must be successful, or the overall
login process will fail. However, even if authentication fails for
this module, the LoginContext continues to attempt
authentication with any other modules in the list. (This can server
to disguise the source of the authentication failure from an
attacker)

REQUSITE

Authentication by this module must be successful, or the overall
login process will fail. If authentication fails for this module, the
LoginContext does not try any further login
modules.

SUFFICIENT

Authentication by this module is not required, and the overall login
process can still succeed if all REQUIRED and
REQUISITE modules successfully authenticate the
user. However, if authentication by this module does succeed, the
LoginContext does not try any further login
modules, but instead returns immediately.

OPTIONAL

Authentication by this module is not required. Whether or not it
succeeds, the LoginContext continues to with any
other modules on the list.
