XML token

XML tokens are offered in two formats, Security Assertion Markup Language (SAML) and Extensible rights Markup Language (XrML).

There is an important distinction between v5.x and v6.0.x and later applications. The information in this article supports v5.x applications only used with WebSphere Application Server v6.0.x and later. The information does not apply to v6.0.x and later applications.

XML-based security tokens are growing in popularity. Two well-known formats are:

Using extensibility of the <wsse:Security> header in XML-based security tokens, we can directly insert these security tokens into the header.

SAML assertions are attached to Web Services Security messages using web services by placing assertion elements inside the <wsse:Security> header. The following example illustrates a Web Services Security message with a SAML assertion token. 

<S:Envelope xmlns:S="...">&
      <wsse:Security xmlns:wsse="...">           <saml:Assertion
                    MajorVersion="1" 
                    MinorVersion="0"
                    AssertionID="SecurityToken-ef375268"
                       Issuer="elliotw1" 
                       IssueInstant="2002-07-23T11:32:05.6228146-07:00"
                     xmlns:saml="urn:oasis:names:tc:SAML:1.0:assertion">                      ...
           </saml:Assertion>       </wsse:Security>  </S:Header>  <S:Body>  ...
 </S:Body> </S:Envelope>
