A few days ago we faced an issue with login into vCenter Appliance Management Interface or VAMI with “Unable to authenticate user” error. It was really strange since we were quite sure the password for the root user was correct. File-based backup needed to be configured on the vCenter Server and as you know this configuration can be applied through the VAMI interface. To make sure the password to the root user has not been changed, we tried to connect to the vCenter Server through SSH, and as expected the password was correct! Strange isn’t it?!
In this article, I will explain how you can solve this issue on the vCenter Server Management interface.

VMware vSAN is Software-Defined Storage(SDS) solution from VMware that is fully integrated into vSphere. To enable vSAN, we need to have a minimum of three ESXi hosts, and each host needs at least one cache disk and one capacity disk. The local disks of ESXi hosts should be formatted by VMFS. Since vSAN is a vSphere clustering feature, we should also have Center Server in place before start implementing it.
If you are a System Administrator or even a Solutions Architect, you might a face a challenge to build a vSAN Cluster with minimum ESXi servers without having a vCenter in place. In many green field environments, vCenter has not been installed and you want to keep ESXi’s disks intact and unformatted. In addition, there are some customers that want to build and manage vSAN Cluster in a separate vCenter and they do not have any additional ESXi host for vCenter deployment.

With access to port 443 of vCenter Server, an attacker may exploit this issue to execute commands with unrestricted privileges on the operating system that hosts vCenter Server. This issue arise because of lack of input validation in vSAN Health Check plug-in.

I could also connect to vCenter Server through SSH but I realized couple of vCenter Server services could not start.
