Description tomek 2004-01-13 15:50:11 UTC
Ive got homes share:

 writable = yes
 browseable = yes
 create mask = 0600
 directory mask = 0700

I put in this share file:
-r--r--r--    1 root     root          444 Jan 14 00:12 rules.txt

In this case users cannot delete or change the file, but they can rename it. I 
think it's serious bug. You can use chattr +i rules.txt to avoid this, however 
extensively using of immutable flag broke my ext3 partition recently (in 
begining I was unable to delete file with no "i" set, after I did chattr -R -
i /home then all permission messed up badly (I use winbind also)

Samba relies on the underlying file system to enforce 
permissions.  I duplicated the behavior you describe 
from windows explorer.  But also from a shell prompt
on the linux server as a normal user.

If you think this is a bug, you'll apparently have to 
convince the file ext2/ext3 maintainers of it.
