Can users login to multiple PC at the same time?

when users try to login to OpenFire server from more than on PC, they get an error “Unable to login due to account already signed in”

is there a way to allow multiple connections to the same account? or logoff the old session?

Inelegant way: second user account.

Second inelegant way: Machine-based Spark login, with user’s full name tagged as the status.
