Here is our penultimate video (that means second last) in our Getting Started with vSphere 5 series.
This video discusses and demonstrates the Lockdown Mode feature in vSphere 5. System administrators can enable the Lockdown Mode feature in order to prevent users from accessing the ESXi 5 hosts directly using the vSphere Client.
Enabling Lockdown mode on an ESXi 5 host will force all users to login via the vCenter Server in order to manage their ESXi hosts.
