posix acl

[Maurizio Marini]

Hi there
the issue is relative to the copy of a file chmod 0700 from an home dir to a
shared public location

if i use samba (windows explorer) to copy the file, the default group acl of destination dir are correctly
applied; if i use cp command in a xterm shell, file is still 0700 and no acl is
applied
Is this a known and old issue with posix acl or i missed a piece?

best regards
Maurizio
