Hello Sys Ads

I would like to create a common account whereby a select number of users know
the password but only one of the users can use it at any one time. If another
user attempts to use it whilst it is in use they should be refused access to
it. Has anyone tried this ?

I guess it needs some kind of locking mechanism ?

Regards

I cannot rember the name of it off hand but there are some daemons you can
run that will limit people to only having one active tty at the same time
if more than one user uses the same account at the same time, it will log
both of them out (after a 1 minute warning)
