Net::SAML2::SP - SAML Service Provider object

=head1 METHODS

=head2 new( ... )

Constructor. Create an SP object.

Arguments:

=over

=item B<url>

base for all SP service URLs

=item B<id>

SP's identity URI.

=item B<cert>

path to the signing certificate

=item B<key>

path to the private key for the signing certificate

=item B<cacert>

path to the CA certificate for verification

=item B<org_name>

SP organisation name

=item B<org_display_name>

SP organisation display name

=item B<org_contact>

SP contact email address

=item B<org_url>

SP organization url.  This is optional and url will be used as in
previous versions if this is not provided.

=item B<authnreq_signed>

Specifies in the metadata whether the SP signs the AuthnRequest
Optional (0 or 1) defaults to 1 (TRUE) if not specified.

=item B<want_assertions_signed>

Specifies in the metadata whether the SP wants the Assertion from
the IdP to be signed
Optional (0 or 1) defaults to 1 (TRUE) if not specified.

=back

=head2 BUILD ( hashref of the parameters passed to the constructor )

Called after the object is created to load the cert from a file

=head2 authn_request( $destination, $nameid_format )

Returns an AuthnRequest object created by this SP, intended for the
given destination, which should be the identity URI of the IdP.

=head2 logout_request( $destination, $nameid, $nameid_format, $session )

Returns a LogoutRequest object created by this SP, intended for the
given destination, which should be the identity URI of the IdP.

Also requires the nameid (+format) and session to be logged out.

=head2 logout_response( $destination, $status, $response_to )

Returns a LogoutResponse object created by this SP, intended for the
given destination, which should be the identity URI of the IdP.

Also requires the status and the ID of the corresponding
LogoutRequest.

=head2 artifact_request( $destination, $artifact )

Returns an ArtifactResolve request object created by this SP, intended
for the given destination, which should be the identity URI of the
IdP.

=head2 sso_redirect_binding( $idp, $param )

Returns a Redirect binding object for this SP, configured against the
given IDP for Single Sign On. $param specifies the name of the query
parameter involved - typically C<SAMLRequest>.

=head2 slo_redirect_binding( $idp, $param )

Returns a Redirect binding object for this SP, configured against the
given IDP for Single Log Out. $param specifies the name of the query
parameter involved - typically C<SAMLRequest> or C<SAMLResponse>.

=head2 soap_binding( $ua, $idp_url, $idp_cert )

Returns a SOAP binding object for this SP, with a destination of the
given URL and signing certificate.

XXX UA
