Hi,

I have the same config as you. And the same problem. I'm trying to fix it since days now, without success. It seems linked to winbind and the IDMAP RID backend. It's working successfully, but I hate those messages in the log files. I have 2 samba servers running the same versions (samba 3.0.24 running on Debian 4.0r1). One samba was installed 2 years ago and it is working, and the 2nd one has been installed this year and I've got these error messages.
I have seen differences in the GROUP MAPPING.
Have a look at this command :

tdbdump /var/lib/samba/group_mapping.tdb

and as well :

net groupmap list verbose

The differences between my 2 servers are linked to group memberships, and now I'm trying to figure out if I can fix things with this command :

net groupmap memberships

But it seems that the BUILTIN\ groups can't be created on systems running Winbind only (as ROLE_DOMAIN_MEMBER)

I'm going back to this ...

regards
Yvan Broccard

Hi,

Since I install Samba 3.0.23d on my Centos5 with kernel 2.6.18-8.1.10.el5 #1 SMP I've the following messages in my logfile:

write list = @DOMAIN+group1
force group = group1

Anybody knows how to fix it?
