permission problems NT-Samba

[Manuela.Arndt at softcon.de]

Dear all,
i have a problem with permissions from NT 4.0 to a Samba-fileserver
(SuSELinux 6.1)
I use standard Backup from NT and backup the files of the sambafileserver.
When I restore the files with permissions-restore the permissions are
different.

original files:
drwxr_xr_x	testuser/testgroup	.
rw_r__r__	testuser/testgroup	test.txt
r_xr_xr_x	user/testgroup		test.sh

I backup it as user from the group testgroup (I have tried to backup it as
User Backup but it makes more problems) then I delete the testfiles
after restore as backup-user with admin users = backup-user the file looks
like that
rw_rw_rw_	testuser/testgroup	test.txt
r_xr__r__	user/testgroup		test.sh

I get also messages in NT-Backup that i have no permissions to set
permissions and at smb.log :
[2000/12/13 07:33:15, 0] smbd/nttrans.c:unpack_nt_permissions(2295)
unpack_nt_permissions: unknown SID used in ACL.

User Backup ist known on Linux with UID 2000. GID 112 (testgroup), testuser
UID 1002

Can someone help me to restore the permissions correct ?

my smb.conf looks like that:

[global]
   workgroup = itservice
   comment = Samba Server
   logfile = /home/administrator/Log/smb.log
   guest account = nobody
   keep alive = 30
   deadtime = 10
   admin users = backup
   os level = 0
   oplocks = False
   security = server
   password server = jupi
   encrypt passwords = yes
   socket options = TCP_NODELAY
   map to guest = Bad User
   local master = no
   interfaces = 172.27.16.14/255.255.255.0
   wins support = no

[WEB_DATA]
   comment = WEB-Projekte developer
   path = /Daten/test
   writable = yes
   create mode = 0777
