An expired or revoked VIP certificate could result in abrupt VIP authentication failures. Certificate expiry notifications are sent to the TECHNICAL contact listed on the VIP Manager account (Click here to update contact information). Visual warnings are also displayed in VIP Manager in the "Notifications" window:
Symantec recommends using a Distribution List email address in the technical contact information to allow delivery of VIP certificate expiration notifications to multiple people.
(Note: Active VIP certificates aren't automatically revoked or expired if a VIP account service-end date lapses as long as the account is renewed within 30 days of expiration.)
VIP certificates provide proof of identity between your Symantec VIP Service account and VIP application (Enterprise Gateway, third-party integration, or custom applications). Certificates management is performed from your VIP Manager account by an administrator with certificate permissions.
