@SiY11:
You could turn off hard and idle timeouts in the CP so they only need to login once, the problem with this is if they use a different network card/computer they must login again.
Ok, this solution sounds good. I think, that ought to work. I'll try this. :)
Thx!
Edit:
hm,
ok I tried … next problem ... each user can now access the internet from this pc. I thought only the user, who was logged in, can access without a new login.
