After upgrading the datacenter from vSphere 4.0 to 4.1 I was unable to connect with my service account “esxuser” by putty or console or Veeam to make some backups, warning message: Access denied
I changed my password a few times.. maybe it was changed, I restarted the SSH service.. no luck.. I created a new account with shell access but still the same deny!
Connect direct your ESX console by VI client, go to Permissions tab and add your service account with Administrator rights:
Yeah, I was able to connect again with my service account.. 🙂
