Hi Mikael,
I have tried with latest ISAM on configuring SAML2 STS chain, there seems to have a condition to be able to set 'SubjectConfirmationMethod' field for SAML2 issue chain: at least one of the 3 types of encryption is selected, i.e. 'Encrypt assertions', 'Encrypt assertion attribute elements', 'Encrypt nameid element'; otherwise the 'SubjectConfirmationMethod' will be ignored.
This condition exists to set 'SubjectConfirmationMethod' is a defect, user should be able to configure 'SubjectConfirmationMethod' without the need to encrypt anything. We'll try to fix this in the next release.
