Subelements of <saml2:Subject> are not parsed correctly

    • Hide
      The <systemitem>SAMLSubjectParser</systemitem> did not support the &lt;saml2:NameID&gt; subelement within the &lt;saml2:SubjectConfirmation&gt; subelement of the &lt;saml2:Subject&gt; element. If it found the &lt;saml2:NameID&gt; subelement, it parsed it incorrectly and threw the following exception:

      <screen>
      java.lang.ClassCastException: com.ctc.wstx.evt.CompactStartElement cannot be cast to javax.xml.stream.events.EndElement
              at org.picketlink.identity.federation.core.parsers.saml.SAMLSubjectParser.parse(SAMLSubjectParser.java:123)
              at org.picketlink.identity.federation.core.parsers.saml.SAMLAssertionParser.parse(SAMLAssertionParser.java:148)
              at org.picketlink.identity.federation.core.parsers.saml.SAMLParser.parse(SAMLParser.java:76)
      </screen>

      This update modifies the <systemitem>SAMLSubjectParser</systemitem> to support the &lt;saml2:NameID&gt; subelement within the previously mentioned elements. The &lt;saml2:NameID&gt; subelement is now parsed correctly and the exception cited above is no longer thrown.

      PLFED is expecting a <saml2:SubjectConfirmationData> subelement within <saml2:Subject>. If it doesn't find one, it will parse the closing <saml2:Subject> tag incorrectly, throwing a ClassCastException:

      java.lang.ClassCastException: com.ctc.wstx.evt.CompactStartElement cannot be cast to javax.xml.stream.events.EndElement
        at org.picketlink.identity.federation.core.parsers.saml.SAMLSubjectParser.parse(SAMLSubjectParser.java:123)
        at org.picketlink.identity.federation.core.parsers.saml.SAMLAssertionParser.parse(SAMLAssertionParser.java:148)
        at org.picketlink.identity.federation.core.parsers.saml.SAMLParser.parse(SAMLParser.java:76)

      This goes against the specification, which does not allow <saml2:SubjectConfirmationData> elements to be direct children of <saml2:Subject>.
