VirtualCenter 2.5 Passthrough Authentication

Stuart Radnidge from vinternals.com discovered how to do pass-through authentication in VMware VC 2.5. This means you will automatically log in to VC 2.5 when the Windows workstation credentials are the same as the ones VC is working with (so this works if you authenticate to the same Windows Domain on both platforms.) The setting is undocumented but is reported to work. You can find the post here. This is how it is done:

To use it, simply add -passthroughAuth -s vchostname to the end of the shortcut used to launch the VI 2.5 client. By default it uses the Negotiate SSPI provider, however since they have fully implemented the interface you can change that behaviour to use Kerberos by adding the following within the <vpxd> node in the vpxd.cfg file on the VC server: <sspiProtocol>Kerberos</sspiProtocol>
