3242858 - SAML does not work after installing/updating to version 13.15.7 or newer


We updated our Signavio Process Manager On-Premise to the version 13.15.7 and since this version, we cannot authenticate ourself with SAML anymore. In the logfile from our Tomcat we see the following error message:

Reason:Invalid SAML Response. Not match the saml-schema-protocol-2.0.xsd

Image/data in this KBA is from SAP internal systems, sample data, or demo systems. Any resemblance to real data is purely coincidental.


In the mentioned 13.15.7 we updated some JAVA libraries and currently the Tomcat is using another library as expected. Please use the following workaround to solve the problem:

  • Stop the Tomcat
  • Open the Tomcat configuration window
  • Open the Java-Tab
  • Add the following two lines to the field "Java Options"

  • Start the Tomcat and try the SAML-integration again
