Hello, In the "Installation_and_licensing_Guide.pdf" there's an option explained that let's one create and options file (idl_lmgrd.opt) in order to manage license usage. There's an example using the 'reserve' keyword to reserve licenses to specific users or groups, but is it at all possible to reserve a particular number of licenses to certain machines no matter who the user is? And on top of that, can the access be time restricted? My scenario is that I want to reserve licenses for 60 computers (30 each in two labs) for a specific time each week (e.g. 8:30 to 10:30 every Friday) and any user can log on to the computer. Is this possible? If anyone can give me some tips or better yet write a sample idl_lmgrd.opt file that would be great. Thanks, Mike
