creating user limitation

Hi
How can i create a user with user manager with max 1 min connection duration?
(Every 1 minute the user must login again)

any idea?
the profile uptime limitation must be used ,is it true?
but it does not work.
Must i activate the profile in user setting or just i must add the profile?
what’s deference between these two selections?

no answer?
I think a feature could be added to manage user’s session timeout control in profiles like WinBox session timeout setting in profiles.
