I did fresh virtual vcenter 5.1 installation, installing all 3 components required and I cannot install with domain admin account via vsphere client. During installation, I remember setting extra long password to admin@system-domain account which was a default set. VMware requires too complex password, so I couldn´t enter my domain admin credentials during installation. I also tried to logon with this account, but unsuccessfully.
Do I need to re-install entire server because of this, and how/what credentials I should use during installation?
Another side question: Is vCenter 5.0 compatible with ESXi 5.1 or do I need to update vCenter as well?
