Konfigurácia IdP

Na začiatok si vygenerujeme “salt”:

openssl rand -base64 36 2>/dev/null

Ďalej pracujeme pod používateľom “idp”

Do konfigurácie attribute-resolver.xml doplníme nový atribút:

vim /opt/shibboleth-idp/conf/attribute-resolver.xml

<!--
Doplneny atribut.
-->
<AttributeDefinition id="eduPersonTargetedID" xsi:type="SAML2NameID" nameIdFormat="urn:oasis:names:tc:SAML:2.0:nameid-format:persistent">
    <InputDataConnector ref="myStoredId" attributeNames="storedId"/>
    <AttributeEncoder xsi:type="SAML1XMLObject" name="urn:oid:1.3.6.1.4.1.5923.1.1.1.10" encodeType="false"/>
    <AttributeEncoder xsi:type="SAML2XMLObject" name="urn:oid:1.3.6.1.4.1.5923.1.1.1.10" friendlyName="eduPersonTargetedID" encodeType="false"/>
</AttributeDefinition>

Príklad konfigurácie attribute-resolver.xml

Ďalej doplníme nový konektor:

<!--
Doplneny datakonektor.
-->
<DataConnector id="myStoredId" 
    xsi:type="StoredId" 
    generatedAttributeID="storedId" 
    salt="Napíšeme salt, ktorý sme si na začiatku vygenerovali" 
    queryTimeout="0">
    <InputAttributeDefinition ref="uid"/>
    <BeanManagedConnection>shibboleth.MySQLDataSource</BeanManagedConnection>
</DataConnector>

V konfigurácii global.xml doplníme potrebné beany:

vim /opt/shibboleth-idp/conf/global.xml

<!--
Doplnene beany
-->
 
<bean id="shibboleth.MySQLDataSource" 
    class="org.apache.commons.dbcp2.BasicDataSource" 
    p:driverClassName="com.mysql.cj.jdbc.Driver" 
    p:url="jdbc:mysql://localhost:3306/shibboleth" 
    p:username="shibboleth" 
    p:password="Heslo pre používateľa shibboleth" />
 
<bean id="shibboleth.JPAStorageService" 
    class="org.opensaml.storage.impl.JPAStorageService" 
    p:cleanupInterval="%{idp.storage.cleanupInterval:PT10M}" 
    c:factory-ref="shibboleth.JPAStorageService.EntityManagerFactory" />
 
<bean id="shibboleth.JPAStorageService.EntityManagerFactory" 
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="packagesToScan" value="org.opensaml.storage.impl"/>
    <property name="dataSource" ref="shibboleth.MySQLDataSource"/>
    <property name="jpaVendorAdapter" ref="shibboleth.JPAStorageService.JPAVendorAdapter"/>
    <property name="jpaDialect">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" />
    </property>
</bean>
 
<bean id="shibboleth.JPAStorageService.JPAVendorAdapter" 
    class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" 
    p:generateDdl="true" 
    p:database="MYSQL" 
    p:databasePlatform="org.hibernate.dialect.MySQL5Dialect" />

Doplníme atribút aj do konfigurácie filtrov attribute-filter.xml:

vim /opt/shibboleth-idp/conf/attribute-filter.xml

<!-- Doplneny atribut - transientId to anyone -->
    <AttributeFilterPolicy id="releaseTransientIdToAnyone">
 
        <PolicyRequirementRule xsi:type="ANY" />
 
        <!-- transientId -->
        <AttributeRule attributeID="transientId">
            <PermitValueRule xsi:type="ANY" />
        </AttributeRule>
 
        <AttributeRule attributeID="eduPersonTargetedID">
                <PermitValueRule xsi:type="ANY" />
        </AttributeRule>
 
    </AttributeFilterPolicy>

Príklad konfigurácie attribute-filter.xml

V konfigurácii saml-nameid.properties doplníme potrebné atribúty - odkazy na beany a salt:

vim /opt/shibboleth-idp/conf/saml-nameid.properties

# Doplnene atributy
idp.persistentId.generator = shibboleth.StoredPersistentIdGenerator
idp.persistentId.dataSource = shibboleth.MySQLDataSource
idp.persistentId.sourceAttribute = uid
idp.persistentId.salt = Napíšeme salt, ktorý sme si na začiatku vygenerovali

Upravíme konfiguráciu saml-nameid.xml odkomentovaním konkrétneho riadku v súbore:

vim /opt/shibboleth-idp/conf/saml-nameid.xml

Odkomentujeme riadok:

<ref bean="shibboleth.SAML2PersistentGenerator" />

Upravíme v konfigurácii ďalší súbor idp.properties:

vim /opt/shibboleth-idp/conf/idp.properties

V tomto súbore doplníme riadok:

idp.consent.StorageService = shibboleth.JPAStorageService

Príklad:

# Set to "shibboleth.StorageService" or custom bean for alternate storage of consent
#idp.consent.StorageService = shibboleth.ClientPersistentStorageService
idp.consent.StorageService = shibboleth.JPAStorageService

Ďalej upravíme súbor subject-c14n.xml:

vim /opt/shibboleth-idp/conf/c14n/subject-c14n.xml

V súbore odkomentujeme riadok:

<ref bean="c14n/SAML2Persistent" />

Príklad:

=======================================================================
Flows used during SAML requests to reverse-map NameIdentifiers/NameIDs.
Below the list are some settings that might be useful to adjust.
=======================================================================
    -->
    <util:list id="shibboleth.SAMLSubjectCanonicalizationFlows">
 
        <!-- The next four are for handling transient IDs (in-storage and stateless variants). -->
        <ref bean="c14n/SAML2Transient" />
        <ref bean="c14n/SAML2CryptoTransient" />
        <ref bean="c14n/SAML1Transient" />
        <ref bean="c14n/SAML1CryptoTransient" />
 
        <!-- Handle a SAML 2 persistent ID, provided a stored strategy is in use. -->
        <ref bean="c14n/SAML2Persistent" />

V metadátach sa bude oznamovať, že IdP podporuje perzistentný identifikátor, do idp-metadata.xml doplníme:

vim /opt/shibboleth-idp/metadata/idp-metadata.xml

<NameIDFormat>urn:oasis:names:tc:SAML:2.0:nameid-format:persistent</NameIDFormat>

Príklad - do elementu IDPSSODescriptor pridáme element napríklad za uvedený element:

<ArtifactResolutionService Binding="urn:oasis:names:tc:SAML:2.0:bindings:SOAP" Location="https://demoidp.sanet.sk:8443/idp/profile/SAML2/SOAP/ArtifactResolution" index="2"/>
<ArtifactResolutionService Binding="urn:oasis:names:tc:SAML:1.0:bindings:SOAP-binding" Location="https://demoidp.sanet.sk:8443/idp/profile/SAML1/SOAP/ArtifactResolution" index="1"/>
 
<NameIDFormat>urn:oasis:names:tc:SAML:2.0:nameid-format:persistent</NameIDFormat>

Vygenerujeme nový WAR súbor:

/opt/shibboleth-idp/bin/build.sh

Spustí sa proces:

Buildfile: /opt/shibboleth-idp/bin/build.xml

build-war:
Installation Directory: [/opt/shibboleth-idp] ?

BUILD SUCCESSFUL

Ďalej pracujeme pod používateľom “root”

Reštartujeme Jetty:

systemctl restart jetty

Logy môžeme kontrolovať v umiestneniach:

/opt/shibboleth-idp/logs

V prípade úprav v adresári /opt/shibboleth-idp/edit-webapp/ je potrebné aktualizovať idp.war a reštartovať Jetty.

/opt/shibboleth-idp/bin/build.sh

systemctl restart jetty
