Hi,

Why is chown is silently failing to chown a file to a winbind user
that is listed in 'getent passwd'?  I can chown to other users on the
system.  I can also chown to arbitrary numbers as long as they do not
match those from winbind.

My guess: "uid == (uid_t)-1" which causes chown to silently fail.
Perhaps getpwnam doesn't work with NSS?

Thank you,

Chris
