The following blog posts discuss SAML2 use cases that have been explored in this series:
SAML v2.0 vs. JWT: SAML2 Single Logout
This post wraps our look at SAML v2.0 Use Cases. The first four use cases are described in “SAML v2.0 vs JWT: SAML2 Web Application SSO Use Cases” and “SAML v2.0 vs. JWT: SAML2 with SOAP Web Services and REST APIs”. The full list of SAML2 vs JWT-related blog posts can be found here.

WS-Security Integrity (XML Digital Signature)
This post continues exploring the use of XML Digital Signature; this time we look at WS-Security Integrity (use of XML Digital Signatures with WS-Security). Our examples show a digital signature and a timestamp in a WS-Security <Security> SOAP Header.
Datapower SOMA Calls
The primary administration automation mechanism on IBM WebSphere DataPower appliances is the XML Management Interface. The XMI interface allows one to make SOMA (SOAP Configuration Management, assuming SOMA = SOap MAnagement) calls to perform various administration tasks. How to perform these…
SOA Specs Visualized
In a previous blog post, I listed a number of SOA Specs and Security Specs that I thought were important to be familiar with when working with DataPower and other SOA technologies. In this post, I made a quick (and dirty) Visio diagram that I tend to draw up on a whiteboard when I’m at a new client…
Some Simple Updates To A DataPower XSLT stylesheet.
In the last post, we saw how an XML Firewall in loopback mode could be used to return a valid SOAP response to a service message. The stylesheet used simply returned a static SOAP response that was independent of the input parameters. The stylesheet returns a response containing the sum of two…
SOAP Web Service Mockup tutorial on DataPower
It is often the case that a DataPower developer will have work to do, but does not yet have a backend Service Provider to point the DataPower service at. In general, anything beyond trivial examples will need to point at something that returns a valid response. In order to satisfy this requirement,…
