If either of the last two numbers are around 300000000 usec (300 seconds), it indicates severe latency in the communication between the vCenter and domain controller.
Environment
VMware vCenter Server Appliance 8.0.x VMware vCenter Server Appliance 7.0.x VMware vCenter Server Appliance 6.7.x VMware vCenter Server Appliance 6.5.x
Cause
SSO uses likewise to contact Active directory environments. The default timeout is set to 5 minutes. In environments where high latency exists between vCenter and Active Directory, reducing the timeout will allow likewise to try other available DCs where less latency exists.
Resolution
To resolve this issue a new value must be added to the registry to control the connection timeout:
Connect to the vCenter Server Appliance with an SSH session and root credentials.
