I was trying to install a Web UI certificate to an Aruba Instant Virtual Chassis, but it failed saying that "cert_upload_validate_certificate_date_faile_txt"
After some troubleshooting I managed to find out that the problem is the expiry date of the intermediate certificate, which was in year 2047.
I strongly believe Aruba is rejecting it because its past the time which can be represented with a 32 bit unix timestamp (which is Jan 19th of 2038).
Can you please look into it and fix this issue in a future firmware revision?
