You can configure the vSphere Web Client to bypass the vCenter Single Sign On server. This allows the vSphere Web Client to connect directly to vCenter Server 5.0 systems that are registered with the vSphere Web Client.
If your environment contains both vCenter Server 5.0 and vCenter Server 5.1 system, you can use this setting to access the vCenter Server 5.0 systems if the vCenter Single Sign On Server becomes unavailable.
The location of this file depends on the operating system on which the vSphere Web Client is installed.
