After upgrading Siteminder release to 12.8 SP5, it was noticed that the SAML Response tags has been changed as seen below which is causing some of the application on the SP side to fail with xml parse issues
Release : 12.8 SP5
Component : SITEMINDER FEDERATION SECURITY SERVICES
The difference in 12.8.5 assertion is due to JAXB Third party library upgrade used by Siteminder .
The all XML NameSpaces used in response are declared and XML NameSpace prefix has been applied for all individual elements by JAXB in 12.8.5
To Note that All these changed are per XML standards only.
Two options should be considered to solve any issue arises from xml parsing on the SP side as follows :
1) Customize the Assertion using the assertion generator plugin to send it in the Format you want
2) The SAML code on the SP side to fix the parsing issue as what is being generated is still per the xml standards
