Can your users log into any of these 300 computers? If so, it it with a
personal login name or as "guest"? Do you want to limit the total time
logged in across all computers, or the total time logged in to any one?
For one computer, timekpr has been resurrected and would do exactly what
you want. For lots of computers and logins that work on any of them, you
might need something better. Or hack it :-)
Integration with Koha (or whatever) will depend entirely upon how
proprietary it is - if it is basically just RADIUS or LDAP or something,
you will be able to hack something up reasonably easily. There are
existing front-ends to those. The authentication side will be easy
anyway - reliably detecting logoffs may be less so. If your
authentication backend is closed, um...
Another way (if the backend is not totally closed) might be to do a
daily export of the user database to something more hackable, and
authenticate just the lab against that. Then you are not tied to e.g.
Koha. Get skilled help though - otherwise you might inadvertently expose
the user details to attack.
How are these lab users authenticating now?
