SAMLSignatureException: failed to verify the XML signature.
After completing a badly needed upgrade from Windows Server 2003 to Windows Server 2008 R2 we are receiving the above message. We are using .NET 4.0 with the SAML2.0 dll.
Please let me know what other information you need.
Your help is appreciated.
If you’d provide SAML trace log, you might get better and quicker answer to this issue, fyi.
Yes, please enable SAML trace and send the generated log file as an email attachment to support@componentspace.com.
