[Samba] New Files do not belong to the User who created them...
Hi Samba-Gurus out there!
Ive got some strange problem here i already tried to track down
searching the net and reading tons of manuals. no luck yet. So now ill
give the Mailing list a try.
The Situation:
############
We run a virtual (VM) Debian Lenny Server as LDAP (OpenLDAP) and Samba
Domaincontroller/Fileserver. The Server also does NFS Exports of the
same Volumes to other Debian Etch Linux Servers around because we have
WINDOWS AND LINUX Users using the same files on the fileserver. So some
access the Server via WINDOWS/SAMBA, some access the Files via
KDE/Linux/NFS.
For Access-Controll we use Linux ACLs (getfacl / setfacl) and
Group-Memberships. Therefor we mounted the Data-Volume with "acl"
parameter. ACLs seems to work fine in any way.
The Problem:
############
Whenever a Linux User creates a File on the Data-Volume, the User itself
becomes "owner", but the file receives the ACLs as defined by the
"default ACLs" of the parent directory. So anything looks fine with
Linux created files yet.
Whenever a Windows User creates a file at the same location, the new
File belongs to "root" and Group "Domain Users". Me and my
Users would
expect the new File would belong to the Creator (User). But for some
reason this is not Happening here. This is just a "cosmetic" problem.
but it confuses the users, because they rely on the user and group owner
informations.
Any Ideas of why is that??? Im lost.
Oh BTW: if i creat a new file within my homedirectory via SAMBA, the
file gets the correct owner (wernera).
THANKS A LOT FOR ANY HELP!
