Hi! Winbind is rather suboptimally reacts to networking changes. I use my notebook in at least 3 different network settings, in one of them I have very probabilistic access to DCs (cisco vpn client is a crap). An nss lookup sometimes takes very looong, sometimes even returns failure. Sometimes I have to login as root and restart winbind to get to my X session past the screensaver. This is far from production quality.
I guess the end-user feeling could be heightened by using cached credentials more agressively. As wast majority of nss lookups are for data already obtained, it might be wise to serve it from cache, and refresh it asynchronously. -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
