Hello,
a customer idp partner of our is changing his own configuration he used to have to connect to our SP.
He said that he changed from A signed SAML Response with an unsigned Assertion/SAMLResponse with Signed Message
to
SAML Response with SignedMessage & Assertion
This generates this error
The problem was fixed on his side reverting this change.
Could you please provide me further information to better understand this scenario?
Thank you
Fabio
