Devices that a user has allocated are not automatically deallocated when the process terminates or when the user logs out. Forcible deallocation is used when a user has forgotten to deallocate a device.
The user or role must have the solaris.device.revoke authorization.
Determine if you have the appropriate authorizations in your role.
$ auths solaris.device.allocate solaris.device.revoke
Forcibly deallocate the device.
In this example, the printer is forcibly deallocated. The printer is now available for allocation by another user.
$ deallocate -f /dev/lp/printer-1
