SAP Business ByDesign

1. Click the icon in the upper right corner.
2. Click My Settings -> Manage Certificates.
3. Click Assign Logon Certificate and see error messages.

The used client certificate does not come from a trusted certificate authority so that ByD doesn't recognize the issuer of the certificate.

Use a valid client certificate from a trusted certificate authority. The trusted certificate authority is listed in Logon Using Client Certificate (X.509). If achieving a valid client certificate is impossible, an SAP Passport can be requested and works in this case.
