Hello, i just searched the archive, but had no luck with my problem. Perhaps
somebody could help me please.. We use Linux with ACL Kernel 2.4.17. EXT3

My samba 2.2.8a server shows different output in the Security Tab of Files
or Directorys..

If i create a new file in linux and set the permissions with setfacl -m to
DOMAIN*GROUP testfile i see in the securty settings the following entrys

(Group) everyone
(Group) unix_group.3302
(Group) unix_group.68

only those entrys with unix_group and no real names..

if i change the settings from windows 2k and add a new user to the list , it
changes to

(Group) everyone
(Group) unix_group.3302
(Group) unix_group.68
(User) robert test (DOMAIN\testuser)
(Group) AD (DOMAIN\AD)

if i change the settings from nt 4.0 it changes to.
(Group) everyone
(Group) unix_group.3302
(Group) unix_group.68
(Group) unix_group.44
(USER) unix_user.432

Why can´t i see real names ?? 

output of getfacl shows
getfacl: Removing leading '/' from absolute path names
# file: webserver/htdocs/fwb/testthomas

That´s one of my problems..

The second one is

If i select a new user and want to give hime some access from NT I select
the user from the user list and after ok I can´t see him in the list.. 
in the log.station i see only those entrys..

  Transaction 474 of length 46

The unable to map error is very abnormal.. also this SID does not exist. It
should be the SID of the new USER or Group .. Why is there a wrong SID in
this List ?

Any hints for me ??

thanks in advance..
