In that case the result in the group permission is based on the MASK value generated as a result of permission inhertance rules. So what you should check is the parent descriptor and look at the inheritable ACEs (default ACL entries in POSIX speak) and compare them with the permissions Xof the newly created files. > Check it with getfacl *and* icacls to get > an idea what it looks like, and compare the result with the POSIX > ACL rules, as outlined on, e.g., http://linux.die.net/man/5/acl.
