[Samba] Access control question.

[Matt Lozier]

Hi Andrew,

Thank you for your response.  The only problem with going this route is that
I really need to have finer grain control over what the users are able to
access.

I have situations where user1 needs to have access to /smbshare/dir1 and
dir3 then user2 needs to have access to /smbshare/dir1/subdir1 and
/smbshare/dir3, but *no* access to /smbshare/dir1.  I suppose that the real
problem lies in the poor setup of the root /smbshare.  However, any changes
to this configuration are out of the question because too many people who
are resistant to change already understand things the way they are ;-)

If I understand LDAP properly (I'm new to this technology) then I should be
able to store user permissions in the LDAP database, no?

Thanks,
Matt

Is it out of the question to create many different shares and then
secure the system on a per-share basis?

I'm securing shares individually using Active Directory.
In each share config I have:
valid users=@MR_ADGROUP_FOR_WRITING @MR_ADGROUP_FOR_READING
write list=@MR_ADGROUP_FOR_WRITING
read list=@MR_ADGROUP_FOR_READING

Create different groups for each share and you're golden.

Of course, this model can be followed without AD.
