Hi Folks,

I am experiencing some problems with samba 3.0.20 which I can not solve
on my own. We have updated from samba 3.0.10 to samba 3.0.20, but I am
not sure when the problems started.

We had a problem with idmap - I had hoped to solve - before. Whenever
we rebooted the server, all of the ACLs got jumbled up. I thought that
our winbindd_idmap.tdb somehow got broken. I re-created it, but still
the problem persists. We use winbindd to get all the Groups and Users
from Active Directory, and we have 2 samba-servers joined to the same
domain. Now I have found out that this could be the cause of the
problem I have with my idmap. Is it a good idea to change winbindd
configuration to windbindd with an NSS/LDAP backend-based idmap
facility? How can I change form local tdb to ldap-tbs without using my
user and group assignsments? I can not afford to loose all or mess up
all the ALCs on the first server. I think this is a bigger issue and
needs to be thought over carefully.

But now to the other problem I have on the second and smaller
samba-server. I have had some trouble concerning access rights where
users were trying to save a file on a share getting "File exits" error
messages. (But the file did not exist before!) After another attempt to
save the same file the operation was successfull. I could not trace the
problem after examining the acls with getfacl on the server. Everything
seemed to be alright.

Here's the global-section of my smb.conf:

# Global parameters
workgroup = DTMS
netbios name = MAX
security = domain
password server = skynet, orion, *
server string = MAX rate one Fileserver
domain master = no
os level = 2
unix extensions = Yes
encrypt passwords = yes
interfaces = eth0

log level = 2
log file = /var/log/samba/%m
max log size = 2048
syslog = 0

acl check permissions = yes
#seems to change nothing...

name resolve order = lmhosts hosts bcast
wins support = no
wins server =

# ************************************************** ******
# winbind section
# ************************************************** ******
winbind uid = 10000-20000
winbind gid = 10000-20000
template shell = /bin/bash
template homedir = /distributed/samba-freigaben/user/%U
template shell = /bin/false
nt acl support = yes
winbind separator = +
veto files = /*.eml/*.nws/riched20.dll/*.{*}/
winbind enum users = yes
winbind enum groups = yes
winbind use default domain = yes
obey pam restrictions = yes

Removing and resetting the acls with setfacl as well as rebooting the
machine did not help either. I have tried to view the ACLS via mapped
Share through windows, but I don't even see the ACLs there. I only see
the local unix-rights (user and owner-group)

I have tried to view and change ACLS for a file named glossar.htm with
the following rights:

max:~ # ls -la /distributed/samba-freigaben/marketing/glossar.htm
-rwxrwxrwx+ 1 jordans Marketing_ges 26190 Apr 11 2001

max:~ # getfacl /distributed/samba-freigaben/marketing/glossar.htm
# file: distributed/samba-freigaben/marketing/glossar.htm
# owner: jordans
# group: Marketing_ges

Here's the configuration for the share marketing where the file
glossar.htm can be found:

comment = Marketing
path = /distributed/samba-freigaben/marketing
nt acl support = no
writeable = yes
browsable = yes
valid users = @ntadmins @RO_Technik @RO_Management
@RO_marketing_intern @marketing_extern
admin users = @ntadmins

comment = Adminshare marketing
copy = marketing
nt acl support = yes
browsable = no
admin users = @DTMS+Domänen-Admins DTMS+WenkP DTMS+JordanS
valid users = @DTMS+Domänen-Admins DTMS+WenkP DTMS+JordanS

I have mapped the Adminshare, that I can see nt acls... But I don't see
the ACLs, I just see the owner (JordanS) and group (Marketing_ges), as
well as root/Max.

Here are the IDs for this user and group:

max:~ # getent passwd |grep 10002
max:~ # getent group |grep 10044
Marketing_ges:x:10044:HeideE,EhrlicC,GibmeiA,Kries eB,partnership,HoefliO,KoriteS,VorbecM,BarossM,Rei terB,DildeiF,LindemY,ConzenN,WirtzP,BockmaA,Zechli T,BuchD,JoergeM,PelkmaR,KottbusM,KartziO,LehmanM

When I try to change permissions via file properties/security tab I get
an Windows "Access Denied" - message... I have turned on Samba log
(loglevel10) and here are some extracts from the messages I get.

We use SuSE Linux 9.1 (i586) and kernel Linux max 2.4.25 with
acl-support (also compiled for samba).

Any ideas? It would be great if someone could offe me help.

Thanks in advance,

Sabine Jordan
