Hello Tobias!
Thanks for the answer. We set "uniqueids" to "never" to allow simultaneous
connections with the same user account. For instance a simultaneous login
from the iPhone and the iPad.
If this "uniqueness" is only determined by the login username and not
further data (like a mac address or name of the connecting device), I see
that this will not work.
Or do you have any other ideas to make this work?
Regards
Sven Anders
