...s can expire during suspend and maybe this situation is not implemented in the winbins code. I don't know if winbind "officially" support suspending. Currently I have written a systemd hook that kill winbind before suspend and restarting it after. 2) The problem appear also on "DHCPDISCOVER". I don't know why but DHCPDISCOVER make winbind react. Just after winbind try to update the "DC" list. I don't understand how winbind know what dhclient do. Maybe a bug in dhclient that close a winbind's opened socket ? But just after after DHCPDISCOVER, winbind lost...

The free DHCP solution, ISC, seems to be having scaling issues (i.e. handling only about 200 DHCPDISCOVER and 20 DHCPRENEW requests), and I was wondering if anyone had any open source suggestions of solutions that could scale much better? (Ideally, I could find a free version of a solution like Nominum, but I know that's asking for much.) Anyone have any suggestions? -- Also on LinkedIn?? Fee...
