Perzisztens attribútum feloldása

Az attribute-resolver.xml konfigurációs fájlban vegyük fel a következő DataConnectort illetve PrincipalConnectort:

<resolver:DataConnector xsi:type="StoredId"
  xmlns="urn:mace:shibboleth:2.0:resolver:dc"
  id="persistentIdConnector"
  sourceAttributeID="uid"
  generatedAttributeID="persistentId"
  salt="valami-random-sztring">
  <resolver:Dependency ref="myLDAP" />
  <ApplicationManagedConnection jdbcDriver="com.mysql.jdbc.Driver"
     jdbcURL=""
     jdbcUserName=""
     jdbcPassword="" />
</resolver:DataConnector>

<resolver:PrincipalConnector xsi:type="StoredId" 
  xmlns="urn:mace:shibboleth:2.0:resolver:pc" id="saml2Persistent"
  nameIDFormat="urn:oasis:names:tc:SAML:2.0:nameid-format:persistent"
  storedIdDataConnectorRef="persistentIdConnector" />

Definiáljuk a persistentId attribútumot:

<resolver:AttributeDefinition id="persistentId" xsi:type="Simple"
  xmlns="urn:mace:shibboleth:2.0:resolver:ad">
    <resolver:Dependency ref="persistentIdConnector" />
    <resolver:AttributeEncoder xsi:type="SAML2StringNameID" 
      xmlns="urn:mace:shibboleth:2.0:attribute:encoder"
      nameFormat="urn:oasis:names:tc:SAML:2.0:nameid-format:persistent" />
</resolver:AttributeDefinition>

Perzisztens attribútum kódolása a SAML válaszba

Az attribute_filter.xml -ben meg kell adni hogy a frissen létrehozott persistentId attribútumot kiadja az SP-nek:

<AttributeFilterPolicy id="releaseNameIDToAnyone">
    <PolicyRequirementRule xsi:type="basic:ANY" />

    <AttributeRule attributeID="transientId">
        <PermitValueRule xsi:type="basic:ANY" />
    </AttributeRule>
    <AttributeRule attributeID="persistentId">
        <PermitValueRule xsi:type="basic:ANY" />
    </AttributeRule>
</AttributeFilterPolicy>
