[Samba] Samba3 shares cannot be mounted on linux box uisng cifs command , error "CIFS VFS: cifs_mount failed w/return code = -13"
well that's peculiar, as I am experiencing something different. in fact
from ADUC I can see all the users belonging to the "domain users"
groups.
the authentication, however, does not work on that group, and the share
"scrap" cannot be accessed with this config:
valid users = @"Domain Users"
however, I have created an auxiliarry group called domainusers , added all
the users to that group and changed the scrap access policy to this:
valid users = @"domainusers"
now all works fine. I am modifying the share in order to never use the
"domain users" groups as after the migration it simly doesn't
work.
maybe this workaround can be helpful for others,
Bye for now!

I don't think you understand this at all :-)
If a user is a member of an AD domain, then they are members of the
Domain Users group, this is done via the ' primaryGroupID' attribute
which should be set to '513'
If you examine the 'Domain Users' object in AD, you will find that it
doesn't show as having *any* users, yet every user is a member and
windows recognises this.
So when you upgrade the 'Domain Users' group to being a Unix group by
giving it a 'gidNumber' attribute and samba on a Unix client is set up
correctly, the Unix machine will also recognise this and allow members
of the 'Domain Users' group access to a share, this will happen even if
'getent group Domain\ Users' show no members of the group. You should
note that you may also use domain_users to reference the group.
