Afaria Setup 4: Install roles – Certificate Authority – NDE

To enroll an iOS device to SAP Afaria, a certificate for this device is needed. For mobile apps, SAP Afaria client can be used to request a user certificate from the CA. All these requests are handled by SAP Afaria, making the certificate handling transparent to the user. For doing this, SAP Afaria needs a CA with NDE enabled.
