I don't doubt the issues with double caching, but perhaps instead of
killing the mosquito with a shotgun, it would be more prudent to use
/etc/nscd.conf to either turn off credential caching or reduce its TTL
to a fraction of winbind's.

That said, I'm not sure caching is the issue here - you seem to have
found the issue I saw as well (UID check with a completely non-local
user).
