Configuring time synchronization on all instances of the VMware Identity Manager service and connector is required for a VMware Identity Manager deployment to function correctly. To configure time synchronization for the VMware Identity Manager service, you use the tab in the VMware Identity Manager console.
You can synchronize the VMware Identity Manager service clock either with the ESXi host or with a Network Time Protocol (NTP) server. By default, the VMware Identity Manager service is set to synchronize with the host.
- As a best practice, synchronize time with an NTP server if the VMware Identity Manager instance can access an NTP server. Otherwise, synchronize time with the ESXi host and configure the ESXi host to synchronize time with an NTP server.
- If your deployment includes VMware Identity Manager service or connector instances on different hosts, the best practice is to synchronize time with an NTP server directly instead of synchronizing with the host to ensure that there is no time drift between the instances.
- In the VMware Identity Manager console, click the Appliance Settings tab.
- Click Manage Configuration and log in with the admin user password.
- Click Time Synchronization.
- Select a time synchronization option.
Option Description NTP Synchronizes the VMware Identity Manager computer system clock with an NTP server. The default NTP server is time.nist.gov. To use another NTP server, enter its fully qualified domain name (FQDN) in the NTP Server text box. For example:
Host Time Synchronizes the VMware Identity Manager computer system clock with the ESXi host. This is the default setting.
