Lock VPN profil to Company PCs only

[wlad50]

Hi,
I got 1 profile *ovpn for all users and making authentification against LDAP Group.
Im looking for way, to prevent users copy this profile on private PCs. I dont want to have in network private computers.

My idea was: Some kind of hidden file, where OVPN check if exists ... or something in this way ...

Any idea ?
Help will be appreciated...
