So if I put a good certificate with the alternative name it'll work OK with this beautiful script? Is that correct? Thanks AndyW

As I remember, this Cmdlet has the same capability as the iLO 5 UI. Is there an option available to add a SAN? Uploading a Custom Cert including a private key seems not possible. — You are receiving this because you commented.

No, it won't. The script is limited to the generated signing request. If the iLO 5 doesn't let you add a SAN you are not able to modify the signing request.

Thanks for the reply. Really appreciate it
