Do you mean the "CN=Administrators,CN=Builtin,DC=chezmoi,DC=priv" group?

Why don't this group appear with the "wbinfo -g" command?

# wbinfo -g

And it's not a normal behavior, isn't it?

Sorry, I don't know how to do that, I'm a samba beginner. I'm going to search, meanwhile, here is the ouput of the "samba -i -M single -d 10" command during the "ls -l /usr/local/samba/var/locks/sysvol/" problem.

Thanks for your help.
