ok, you are right, that's more I argued from the bug report. Reading the
bug report I can argue that winbind assign as a primary group "Domain
Users" even if the primary group is another group. This happen in idmap
rid and idmap ad. This happen to real users or PC users. Do you agree?
There is a link between this bug and the PCs home folders I found in the
users home directory?

I'm confused... this bug affect any samba version I used, affect even
old versions and I hope doesn't depend from the members samba versions
installed

Ok, so do you think that home folders are created because PC "users"
have "Domain Users" as a default group so do you suggest me to add
this
problem to the bug report... but are you sure?
