RSA Issue with Windows SSO

    Applies to:
  • Legacy SecureAuth IdP
Deployment model:
  • On Premises
  • SecureAuth version affected: All


    You will see a RSA error from the SA server when trying to use SAML assertion or message signing with the use of WindowsSSO.


    There can be numerous causes to this issue, mainly some sort of certificate issue, which can comprise of:

    • Permission
    • Loss of private key
    • Wrong certificate/None selected


    Verify the cause of this issue and proceed through process of elimination to deduct the culprit.


    1. First verify if this indeed only does happen with SAML assertion or message signing by turning those flags to false and see if the SAML works after.

    2. If the error still occurs, we will look at the certificates by going to the certificate console.

    3. Expand Personal certificates > right click on your certificate > All Tasks > Manage Private Keys

    4. Ensure that Authenticated Users has at least Read access to the private key.

    5. Once that is good to go, re-enable SAML assertion signing and you should be good!
