When importing a certificate into the SSO Certificate Data Store, we receive the following error in the Administrator UI.
"Error: Certificate importer failed attempting to process the selected file."
Reviewing the Server.log for the WAMUI we see the following error.
"invalid DER-encoded certificate data"
This error occurs when the certificate file containing invalid formatting characters or carriage returns.
Any Certified SSO Environment
Reviewing the certificate in a text editor, we can see that the following lines are not present.
Ensuring that the first line starts with -----BEGIN CERTIFICATE----- and ends with -----END CERTIFICATE----- should resolve this issue.
