1. conf/idp.propertiesのidp.authn.flowsに有効にする認証フローを設定します。

   コード ブロック
   language diff title idp.properties collapse true
   # Regular expression matching login flows to enable, e.g. IPAddress|Password -idp.authn.flows= Password +idp.authn.flows= Password|RemoteUser|X509

2. 認証結果を保持している認証フローを優先するために、conf認証結果を保持している認証フローを優先するために、conf/idp.propertiesのidp.authn.favorSSOをアンコメントします。

   コード ブロック
   language diff title conf/idp.properties collapse true
   # Whether to prioritize "active" results when an SP requests more than # one possible matching login method (V2 behavior was to favor them) -#idp.authn.favorSSO = true +idp.authn.favorSSO = true

   


3. conf/authn/general-authn.xmlのshibboleth.AvailableAuthenticationFlows内の認証フローを弱い認証フローから強い認証フローの順に並べます。各認証フローのsupportedPrincipalsプロパティに下記を追加します。

   認証フロー	supportedPrincipalsプロパティ
   Password	継承元のshibboleth.AuthenticationFlowで定義されているsupportedPrincipals, Level1
   RemoteUser	Level2, Level1
   X509	Level3, Level2, Level1

Password認証フローのExtendedフロー

設定

1. 認証フローの階層化の設定を行ってください。

2. conf/authn/general-authn.xmlのauthn/PasswordにExtendedフローで利用するLevel2, Level3を追加します。

   コード ブロック
   language diff title conf/authn/general-authn.xml collapse true
   <bean id="authn/Password" parent="shibboleth.AuthenticationFlow" p:passiveAuthenticationSupported="true" p:forcedAuthenticationSupported="true"> <property name="supportedPrincipals"> <util:list> <bean parent="shibboleth.SAML2AuthnContextClassRef" c:classRef="urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport" /> <bean parent="shibboleth.SAML2AuthnContextClassRef" c:classRef="urn:oasis:names:tc:SAML:2.0:ac:classes:Password" /> <bean parent="shibboleth.SAML1AuthenticationMethod" c:method="urn:oasis:names:tc:SAML:1.0:am:password" /> <!-- --> <bean parent="shibboleth.SAML2AuthnContextClassRef" c:classRef="urn:mace:gakunin.jp:idprivacy:ac:classes:Level1" /> + <!-- Extended Flows --> + <bean parent="shibboleth.SAML2AuthnContextClassRef" + c:classRef="urn:mace:gakunin.jp:idprivacy:ac:classes:Level2" /> + <bean parent="shibboleth.SAML2AuthnContextClassRef" + c:classRef="urn:mace:gakunin.jp:idprivacy:ac:classes:Level3" /> </util:list> </property> </bean>

3. conf/authn/password-authn-config.xmlでExtendedフローのでExtendedフローのbeanをアンコメントします。

   • shibboleth.authn.Password.ExtendedFlowsのc:_0に、ExtendedフローとするRemoteUserとX509を設定します。

   • shibboleth.authn.Password.PrincipalOverrideに、Password認証フローで認証するLevel1を追加します。

   コード ブロック

   <!-- Configuration of "extended" login methods to offer in the password login form. The String bean is a regular expression identifying the flows to offer. These flows must also be enabled at the "top" level to be available for use. The ExtendedFlowParameters bean can be used to transfer custom parameters from the login form into the context tree for use later by other flows.
