Ok. That's clear. But what is > stored in the "lock directory" and what is the reason why its content > isn't placed in one of the other two directories?
locks are for things that can (and should) go away at shutdown. cache is for things that are handy to have, but can be re-generated without major cost (which makes it fiddly, as you then get to your next question) > *Question 2*: Why is the "winbindd_cache.tdb" stored in the state > directory? Isn't it just a cache file? The issue is that if this is treated as cache, and destroyed, then offline logins fail after a reboot on a system that chooses to purge such cache files. I think there may also be some other persistent data in there as well (others I hope will clarify). At least that is how I understand the issue.
