How to maintain session across VCP client and backend integration server?

Hi,

We are building a vSphere client plugin with workflows offloaded to a backend server.

Is there way using which I can use the logged in user session to run these flows in the backend server?

I am looking for a possibility to either using the logged on session on client to run server flows, or a possibility to impersonate based on logged on user.

Can someone point me to a best practices in case of VCP plugin in this respect.

Thanks
