Authen::Passphrase::AcceptAll - accept any passphrase


	use Authen::Passphrase::AcceptAll;

	$ppr = Authen::Passphrase::AcceptAll->new;

	$ppr = Authen::Passphrase::AcceptAll

	$ppr = Authen::Passphrase::AcceptAll

	if($ppr->match($passphrase)) { ...

	$passphrase = $ppr->passphrase;

	$passwd = $ppr->as_crypt;
	$userPassword = $ppr->as_rfc2307;


An object of this class is a passphrase recogniser that accepts any
passphrase whatsoever.  This is a subclass of L<Authen::Passphrase>, and
this document assumes that the reader is familiar with the documentation
for that class.

This type of passphrase recogniser is obviously of no use at all in
controlling access to any resource.  Its use is to permit a resource to
be public in a system that expects some type of passphrase access control.

# There is only one object of this class, and its content is
# insignificant.



=item Authen::Passphrase::AcceptAll->new

Returns an accept-all passphrase recogniser object.  The same object is
returned from each call.


	my $singleton = bless({});
	sub new { $singleton }

=item Authen::Passphrase::AcceptAll->from_crypt("")

Returns an accept-all passphrase recogniser object.  The same object is
returned from each call.  The argument must be the empty string.


sub from_crypt {
	my($class, $passwd) = @_;
	return $class->new if $passwd eq "";
	return $class->SUPER::from_crypt($passwd);

=item Authen::Passphrase::AcceptAll->from_rfc2307(USERPASSWORD)

Generates a new accept-all passphrase recogniser object from an RFC
2307 string.  The string must consist of "B<{CRYPT}>" (case insensitive)
followed by an acceptable crypt string.


=head1 METHODS


=item $ppr->match(PASSPHRASE)

=item $ppr->passphrase

=item $ppr->as_crypt

=item $ppr->as_rfc2307

These methods are part of the standard L<Authen::Passphrase> interface.
The L</match> method always returns true, and the L</passphrase> method
returns the empty string (the shortest of the infinite number of correct


sub match { 1 }

sub passphrase { "" }

sub as_crypt { "" }
