Yes I can see that ;-)
I can also see why, your problem is that you are using the Unix
Lets see if can explain this ;-)
First and foremost, all your users are Windows users and your groups
are the same.
When you want a user to be a Unix user as well, you add the required
RFC2307 attributes, the same goes for groups.
Just use the 'Unix attributes' tab to add the required attributes and,
if you are using a version of Samba before 4.6.0, Ensure the primary
group is set to Domain Users, from 4.6.0, you can change it to any
group that has a gidNumber.
If you create a group, lets call ours 'unixgroup', you would first
create it as a Windows group, you would then add a gidNumber attribute
using the 'Unix attributes' tab for the group. The group 'unixgroup'
would then be a Windows group AND a Unix group.
Now this is where you are going wrong, you do not add Unix users to
a Unix group by using a 'Unix attributes' tab, you can, but it will
not do anything from a Unix perspective (or Windows, come to that).
Remember what I said about all users & groups being Windows ones ? Just
add the Windows/Unix users to the Windows/Unix group using the standard
Windows tools and Unix will see them as Unix users of Unix groups
So, to shorten the above:
Create user & groups
Extend to Unix users & groups with the 'Unix attributes' tab
Pretend they are just Windows users when adding the users to a group.
Hope this helps, but feel free to ask any questions.
