Dear community,
recently we faced the following issue in our infrastructure.
We have two identity collectors running on WindowsServer 2012R2. The certificate under Mobile Access --> Portal Settings on one of our gateways was changed to a new wildcard certificate. The previous certificate was also a wildcard. The gateway is R81.10.
As a result of the change, both identity collectors displayed "Gateway Certificate Untrusted", until we performed an update certificate info. The "update" action was performed two weeks after the certificate replacement!
IA rules on the gateway were functioning normally for the two weeks period! We are trying to understand why we did not face any service disruption during this time. Identity awareness logs on the gateway show that AD user/group information was updated to the firewall. If the trust between identity collector/firewall is broken, how is this possible?
