[Samba] Multiple Samba Instances: Cannot set private dir and lockdirectory in smb.conf

Hi,

four years ago someone has tried to run two independent instances of
samba on one machine:
http://lists.samba.org/archive/samba...st/091500.html

I would like to do that, too.
Are there still hardcoded file locations, that cannot be overwritten in
smb.conf?

My samba version: 3.0.28a

These parameters in my /var/samba/etc/smb_SMBTEST1.conf do not help:

log file = /var/log/samba/SMBTEST1/log.%m

pid directory = /var/run/samba/SMBTEST1
lock directory = /var/run/samba/SMBTEST1
private dir = /var/run/samba/SMBTEST1

It is possible to run more than one instance. I did not find out any
interference, yet. But they still access the same files in the standard
encoded path:

As well as samba first logs into /var/log/samba/log.nmbd and then
continues with /var/log/samba/SMBTEST1/log.nmbd.

I would not like to compile samba new, as I do not like separate
binaries for each instance.

Ideas wellcome.

Thanks
Christian

yes. I can't think of any case where each would need it's own
set of tdb files. but each will need it's own smb.conf obviously.
Winbind is the exception. You cannot currently run multiple
instances of winbind without some severe trickery and path hacking
in the source code I don't think.
