Foreman seems to create a login session for almost every action done on a vsphere cluster, like: powerstatus, editting, etc.
I have tried tweaking fog by editting the @vsphere_must_reauthenticate = false to true from fog/lib/fog/vsphere/compute.rb and restarting foreman, but it still opens a new login session for almost every action.
I must say i'm not exactly sure what the @vsphere_must_reauthenticate should accomplish.

Neither am I sure if this is a fog or a foreman issue, or both.

During these actions I monitored new connections from our foreman server to the vsphere console, new connections are opened when doing a refresh of the status page or doing an edit.
which seems to result in a new session on the vsphere console.

I believe it should try to reuse connections and/or sessions where possible.
