[Samba] Domain Member Server: Domain Users cannot access shares

Hello to the Samba devs and mailing list subscribers,

I've run into a bit of trouble getting a new domain member server setup.

I've got three Ubuntu 14.04 64 bit VMs running the latest stable build of
Samba built from source acting as Domain Controllers.  I've got a fourth
physical machine running Ubuntu 16.04 64 bit running the canonical
distribution samba (Version 4.3.9-Ubuntu) that I've configured as a Domain
Member Server providing file sharing for the domain.  Shared directories
are stored on a RAID 1 array formatted ext4.  Currently I can see and
access all shares using any account that is a member of the Domain Admins
group, and can alter Share Permissions and ACLs via the Security tab via
the Computer Management snap-in running on a Windows 7 workstation that is
joined to the domain.  I've reset all ACLs and executed chmod g=rwx /mnt
and chgrp "DOMAIN\Domain Admins" /mnt and granted "Everyone"
and "Domain
Users" Full Access in both the Share PErmissions and Security tabs.  Any
attempt to view shares on the domain member server when logged in as a user
who is a member of the "Domain Users" group fails, I am prompted to
enter
credentials, I do so and the are rejected.  Domain Admins can both view all
shares and access their contents without a problem.

[Samba] Domain Member Server: Domain Users cannot access shares

So it seems that I have identified the source of all of my permissions
issues, though I'm unclear as to exactly why these problems have occurred
and would love an explanation if anyone can offer one.

I was using mdadm to create a RAID 1 array, formatting it ext4 and storing
all of the data that samba was serving on /dev/md0.  The two drives that
make up the array are hosted by an LSI MegaRaid controller, though they are
not configured within it's interface.  After carefully troubleshooting
every step in the process of setting share permissions and ACLs I decided
to create a test share on the system drive. I copied one of the problematic
directories from the raid array to my home folder and was immediately able
to access it as a Domain User... So something about the RAID array is
causing the failure.  I've since moved all of the shared data to the system
drive and am moving on to other tasks but I'd really like to get it moved
back to the array.

What is going on here?  The system drive is hosted by the same
controller... I've successfully used RAID arrays and mdadm to host shares
at other locations.  I'd really love to understand what's going awry in
this setup.

Kind regards,

JS

[Samba] Domain Member Server: Domain Users cannot access shares

Your raid setup may be the main culprit here, but your Samba setup
isn't helping.

Can I suggest a few alterations ?

Remove the gidNumber from these groups:

group policy creator owners
enterprise admins
schema admins
dnsadmins

Remove the uidNumber from this user:

administrator

Add this line to smb.conf:

username map = /etc/samba/user.map

Then create the user.map

nano /etc/samba/user.map

!root = PHM\Administrator PHM\administrator Administrator
administrator

Remove all the instances of 'admin users' & 'valid users'
from the
shares. Use Windows ACLs instead, see here for more info:

https://wiki.samba.org/index.php/Shares_with_Windows_ACLs

Try running 'getfacl /mnt/md0/samba_shares/Accounts'

You can do it with ADUC, or you can use ldb or ldap tools or ADSI edit.

Not too sure about the documentation, There is some in 'man smb.conf',
but it is easier to describe it to you.

On a Samba AD DC, Administrator gets mapped to root automatically, but
on a domain member it isn't. There are two schools of thought here,
one is to give Administrator a uidNumber, but I don't recommend this.
If you do give Administrator a uidNumber, it becomes just another
Unix user with just the same permissions as any other user and it
breaks the DC. The other option is to use a 'username map', this will
do what the DC does and maps Administrator to the root user.

[Samba] Domain Member Server: Domain Users cannot access shares

Hi Rowland,


*Apparently I accidentally replied directly to you instead of the list,
this is from a couple days ago...*

First off, thanks again for your help, your insight is invaluable.

I have completed the changes you suggested:

I've used ADUC to remove the NIS Domain and UID/GID number from the
following Users/Groups:

   - group policy creator owners
   - enterprise admins
   - schema admins
   - dnsadmins
   - Administrator

I've added "username map = /etc/samba/user.map" to my smb.conf

I've created /etc/samba/user.map

ls -la /etc/samba/user.map
-rw-r--r-- 1 root root 73 Sep 21 20:53 /etc/samba/user.map

cat /etc/samba/user.map
!root = PHM\Administrator PHM\administrator Administrator administrator

Here is the output of the getfacl command you requested I run:

sudo getfacl /mnt/md0/samba_shares/Accounts
getfacl: Removing leading '/' from absolute path names
# file: mnt/md0/samba_shares/Accounts
# owner: itwerks
# group: domain\040admins
user::rwx
group::rwx
other::rwx
default:user::rwx
default:group::rwx
default:group:domain\040admins:rwx
default:mask::rwx
default:other::rwx

JS

[Samba] Domain Member Server: Domain Users cannot access shares

*Another reply that was accidentally sent to the wrong address...*

I ran another test of a share on the raid array after making the changes
you suggested Rowland.  I reset the ACLs on /mnt/md0/samba_shares/test as
outlined in the wiki and set the default group to domain admins.  I
executed setfacl commands g=rwx and chgrp domain admins, then added the
directory to my smb.conf and ran "smbcontrol all reload-config".  I
then
logged in to a Windows box as administrator and set ACLs for my test domain
user account, allowing full control in both share permissions and the
security tabs, applied settings and closed the snap-in.

I then logged in to another machine as my test user and tried to access the
new share and still received access denied.

I'd be oh so happy if this thread ends and the raid controller isn't the
root cause of this issue, but my gut says it must be as shares that I
copied from the array to the system drive retained the ACLs I had set
previously and we're accessible without modification.  I just wish I could
find some indication that this is a known issue, my Google fu fails to
reveal any evidence supporting the theory.


Kind Regards,

JS
