Allow Students To lock Rather Than Log Off?

[SSFC]

We have had a slight problem this week, it seems a student used another students account to send email messages while the original student was away from the pc talking to the teacher. In our college we have a policy of not letting students lock their computers in case they abuse this facility (leave them locked).

 

Is there a way of letting student lock there accounts but then log them off after a period of time if they are not used?

 

I have found some ways of doing this but i wish to:

 

1) Vary the log off time in labs to that in the lrc and open access areas

2) Not have a time limit on how long a teacher can lock a machine

3) Still allow staff and students to use the same manditory profile

 

If anyone has any ideas their help would be greatly appreciated.

 

Thanks

staff and students have different profiles here for a whole range of reasons.

 

If a kid leaves the machine locked we tell other students to just reboot the computer. Tough luck for whoever left it like that.

 

Force shutdowns at night will prevent any lockings in the morning at least!
