My plan is to eliminate the need for an user logged into the OpenERP web interface having to log into my php system.

So, having that in mind, I would like to clarify the following:

• First hand, is it possible to request a check on either there is or not an user logged in from the current web browser and return their user id or username and the database they are on?
• If so, which xmlrpc endpoint should I direct the request? ( xmlrpc/common or xmlrpc/object )
  • What are the parameters to be sent?

I would only require the user to login in case OpenERP respond saying that no one is logged into the OpenERP Web Interface.
