AD (used by {{TenantName}}) and NAS controller {{nodeId}} clocks aren't synchronized Description: Clock of NAS controller {{nodeId}} and AD clock, used by {{TenantName}} (domain {{DomainControllerName}}), are not synchronized (skew of {{adClockSkew}} seconds exceeds critical threshold of {{maxAdClockSkew}} seconds). Kerberos authentication may fail. Fix system clock/Fix AD clock. Enter the time configuration screen and get the configured NTP host. If no NTP is configured, it is recommended to configure one by either using the organization's NTP or the same IP/name used for joining the NAS to the AD.
