I did not get any response . pinging it again.

Dear samba team,
 please help me in understanding these.

1) in samba posix_acls.c why samba always setting the READ access for
the file and READ and WRITE access for directory ?
case S_IRUSR:
		/* Ensure owner has read access. */
		pace->perms |= S_IRUSR;
		if (is_directory)
			pace->perms |= (S_IWUSR|S_IXUSR);
		and_bits = unix_perms_to_acl_perms(and_bits, S_IRUSR,
		or_bits = unix_perms_to_acl_perms(or_bits, S_IRUSR,

2) I have connected a samba share from the device onto my windows xp
machine.. when I tried modify subfolder owner  write permissions , it is
simply ignoring that and setting the write permission again. ofcourse
acl are enabled on that share.
