Hello

What do you mean, I dont get it clear?
Do you mean a fe_user logs in on site-A and then goes to site-B.. and 
site -B should know that the user was logged in at site-A ?
  If you want it in this way it is difficult, because of the diffrent 
Domains of the sites: cookies from site-A are not send to site-B by the 
browser. (A strange solution for that could by that you add a paramter 
to the link from site-A to site-B so that site-B has a chance to 
identify the session.)
