problem with dos filemode

[D. van Leeuwen]

Hello,

I have a problem with Samba's 'dos filemode'.

----------------------->8------------------------
First, my smb.conf is:
# Samba config file created using SWAT
# from localhost (127.0.0.1)
# Date: 2001/09/07 16:05:48

# Global parameters
[global]
 workgroup = SYENSNET
 netbios aliases = printserver
 server string = Syens samba server
 encrypt passwords = Yes
 map to guest = Bad User
 domain logons = Yes
 os level = 65
 domain master = True
 dns proxy = No
 wins support = Yes
 printing = cups

[test]
 comment = Hans' test directory
 path = /home/tst
 admin users = admin
 read only = No
 directory mask = 0775
 inherit permissions = Yes
 dos filemode = Yes
-----------------------8<------------------------

In /home/tst/ is the following directory:
----------------------->8------------------------
drwxrwxr-t    7 syens    syens         527 Sep 19 15:47 .
drwxrwxr-x    3 syens    syens          59 Aug  8 14:30 ..
-rwxrw-r--    1 jurgen   syens       33280 Sep 19 15:47 3EBA9100
-rwxrw-r--    1 jurgen   syens       35840 Sep  7 15:36 katja.doc
drwxrwxr-x    3 jurgen   syens         176 Sep  6 17:23 map_jurgen_00
-rwxrw-r--    1 katja    syens      183808 Sep 19 15:46 tst_jurgen_00.doc
-rwxrw-r--    1 katja    syens       33280 Sep 19 15:46 tst_jurgen_00.xls
-rwxrw-r--    1 katja    syens       70144 Sep  7 14:23 tst_katja.doc
-----------------------8<------------------------
With the option 'dos filemode = Yes' I expect user jurgen to be able to
delete the file tst_jurgen_00.xls.
This is not the case.

Editing the file in Excel (Excel 2002) fails too: on saving Excel first
creates a
temporary file (3EBA9100 in this case) which is renamed to the destination
file. This rename fails because
user jurgen doesn't have delete rights on a file of user katja.

Has someone a clue what is going wrong?
System info:
syens1:/home/tst/Algemeen # uname -a
Linux syens1 2.4.4-64GB-SMP #1 SMP Fri May 18 14:54:08 GMT 2001 i686 unknown
syens1:/home/tst/Algemeen # smbd -V
Version 2.2.0a
The whole system is running on a reiserfs file system.

Cheers,

Hans
