Lock a screen after inactivity with CDE

I?m running Solaris 8 with a CDE environment and would like the screen to lock after a specific period of inactivity.

I would like this to be machine wide rather than user based.

I think you can edit the file dt.resources in $HOME/.dt/sessions/current and add the entries:

dtsession*extension.lockTimeout: 120
dtsession*extension.saverTimeout: 15

But this would only apply for that user, not machine wide. I have quite a number of Sun machines to apply this function to!

Any help would be much grateful.
