It looks like 'bacci' is a normal user and the owner of the
Policies GUID dir should be 'Domain Admins'

This is where one of the problems start, bit of a catch 22 problem, you
need to give 'Domain Admins' a gidNumber to be visible to Unix, but if
you do, it looses the 'ID_TYPE_BOTH' from idmap.ldb that means it can
own dirs & files in sysvol.

You will need to look inside idmap.ldb to find this.

Don't give the BUILTIN users & groups uidNumbers & gidNumbers, let
samba do this on the DC and set up smb.conf correctly on the domain
member. You do this by using 'idmap config * : backend = tdb'

[Samba] Problems with GPO

Hi,

bacci user is Domain Admin, because 30049 group is Domain Admin member. I
use this user to create GPO.

Following are my configurations files:

*FILE-SERVER - SMB.CONF*
[global]
  netbios name = file-server
  workgroup = EMPRESA
  security = ads
  realm = EMPRESA.COM.BR
  encrypt passwords = yes
  dedicated keytab file = /etc/krb5.keytab
  kerberos method = secrets and keytab
  preferred master = no
  idmap config *:backend = tdb
  idmap config *:range = 1000-3000
  idmap config EMPRESA:backend = ad
  idmap config EMPRESA:schema_mode = rfc2307
  idmap config EMPRESA:range = 10000-9999999

  winbind nss info = rfc2307
  winbind trusted domains only = no
  winbind use default domain = yes
  winbind enum users = yes
  winbind enum groups = yes
  winbind refresh tickets = yes

  vfs objects = acl_xattr
  map acl inherit = Yes
  store dos attributes = Yes
  username map = /etc/samba/user.map


*DC1 - SMB.CONF*
[global]
    workgroup = EMPRESA
    realm = EMPRESA.COM.BR
    netbios name = DC1
    server role = active directory domain controller
    dns forwarder = 192.168.200.10
    idmap_ldb:use rfc2307 = yes

[netlogon]
    path = /opt/samba/var/locks/sysvol/empresa.com.br/scripts
    read only = No

[sysvol]
    path = /opt/samba/var/locks/sysvol
    read only = No


*DC2 - SMB.CONF*
[global]
    workgroup = EMPRESA
    realm = EMPRESA.COM.BR
    netbios name = dc2
    server role = active directory domain controller
    idmap_ldb:use rfc2307 = yes

[netlogon]
    path = /opt/samba/var/locks/sysvol/empresa.com.br/scripts
    read only = No

[sysvol]
    path = /opt/samba/var/locks/sysvol
    read only = No


I'm using "samba-tool drs showrepl" command in DC2 and the result
is
SUCCESS.

Do I have need to remove the Unix attributes of all builtin users
(Administrators, Accout Operators, Users, Guest, ...)? Do Domain Users,
Domain Admins, Domain Computers Groups also to need remove Unix Attributes?

Do I have just select the "None" option in the Unix Attributes tab (in
the
RSAT) to remove it?

Have the accounts of the domain computers (joined in domain) must have the
Unix attribute ?

Is there way to remove null objects of Samba 4 ?

*Others Tests*

Result of "*testparm*" command:

The only possible problem with your smb.conf files (and it doesn't have
anything to do with your problem) is the second DC doesn't have a
forwarder.

The only Group that may need a gidNumber is Domain Admins, the only
only group that must have a gidNumber is Domain Users and then only if
you use the winbind 'ad' backend on a domain member.

This looks like a dns problem, plus the command should be:

samba-tool gpo list bacci

This is definitely a dns problem

[Samba] Problems with GPO

Just make it yourself a bit more easy. 

Setup sysvol like this. 

[sysvol]
        path = /home/samba/sysvol
        read only = No
        acl_xattr:ignore system acls = yes

Restart samba, and set the SHARE RIGHTS and File/Folder rights again. 
Or atleast check them, the defaults should be ok. 

When thats done. 
Go here. : 
http://trekker.net/archives/group-policy-downloads/ 
get the ADMX templates you need. 

Win 10 build 1607 is not on that site, found here : 
https://www.microsoft.com/en-us/download/details.aspx?id=53430

and for otheres, install this in win 7 and copy the templates to the sysvol.
( located somewhere in programfiles ) 

Extra usable templates here:
http://winintro.com/ 

now, when thats done, and this if more for you. 

Does the user bacci need Domain Admin. 
Like is it you replacement for user Administrator?  Then thats ok. 
If its a normal user which needs todo GPO stuff. Then i suggest adding this user
to "Group Policy Creator Owners" and dont abuse the domain admin
group.

So this is the basic stuff go a GPO setup. 


Now, about the error : 
ERROR(runtime): uncaught exception  ... 
You can ignore it IF you use the parameter : acl_xattr:ignore system acls = yes 
Or, move all folder from sysvol, do the sysvol reset, and place the folders
back, that can help.

I do advice to setup GID for "Domain -" Users/Admins/Guest and most
important. "Domain Computers" .. now we are getting to you problem.

Due to all MS changes, how policies are applies has changes. 

The user setting is not applied anymore by the user, but by the computer.
This is key to remember. 

So for every policy you set you need one the these groups. 

1) authenticated users  ( users and computer accounts ) ( preffered ) 
2) Domain users + any group  this is a group for applying the GPO. 
3) Domain computers/ any computer group 

In option 1, nothing special is needed.
In option 2, you must set read GPO polices for domain users, and read+apply for
the custom group.
In option 3, same as option 2. but this is only for a computer policie. 

If you have problem like, GPO applies from one server, but the other dc. 
Run : net cache flush 
Stop samba on both DC's and copy the idmap.tdb from DC1 to DC2. 


About you setup and config, looks all fine to me, exept.
> 117, in dc_url
>     raise RuntimeError("Could not find a DC for domain", e
Please post you resolv.conf /etc/hosts /etc/nsswitch.conf
And are you using bind_DLZ or internal samba DNS

Louis

If you dont add them and the idmap is out of sync somehow, you get GPO errors.
So i suggest, untill the BUILDIN\groups are all correct mapped in samba, give
domain computers a GID. This can really help with GPO problems.

/etc/samba/smb.conf (only a piece)

idmap config EMPRESA:schema_mode = rfc2307
idmap config EMPRESA:range = 10000-9999999
winbind nss info = rfc2307
...

I copied idmap.ldb from DC1 to DC2, now uidNumber and gidNumber are the
same. But in File Server is still different of the DC.

I would like to remove without reference objects in my Domain. (Ex: SID:
S-1-22-33-55 "unknown"). Is Possible ?



*GPO List has still problems*
root at DC1:/opt/samba/private# samba-tool gpo list ferreira
ERROR(runtime): uncaught exception - ('Could not find a DC for domain',
RuntimeError('NT_STATUS_NETWORK_UNREACHABLE',))

line 175, in _run
    return self.run(*args, **kwargs)
  File "/opt/samba/lib/python2.7/site-packages/samba/netcmd/gpo.py",
line
349, in run
    self.url = dc_url(self.lp, self.creds, H)
  File "/opt/samba/lib/python2.7/site-packages/samba/netcmd/gpo.py",
line
117, in dc_url
    raise RuntimeError("Could not find a DC for domain", e)

In DC1 has 2 pastes in Sysvol\empresa.com.br: Policies and Scripts. But in
DC2, the Policies paste there isn't. Is this normal?

I'm using *INTERNAL Samba DNS*. Following my DNS tests:

root at dc1:~# host -t SRV _ldap._tcp.empresa.com.br.
_ldap._tcp.empresa.com.br has SRV record 0 100 389 dc1.empresa.com.br.
_ldap._tcp.empresa.com.br has SRV record 0 100 389 dc2.empresa.com.br.

root at dc1:~# host -t SRV _kerberos._udp.empresa.com.br.
_kerberos._udp.empresa.com.br has SRV record 0 100 88 dc1.empresa.com.br.
_kerberos._udp.empresa.com.br has SRV record 0 100 88 dc2.empresa.com.br.

root at dc1:~# host -t A dc1.empresa.com.br.
dc1.empresa.com.br has address 192.168.200.25
root at dc1:~# host -t A dc2.empresa.com.br.
dc2.empresa.com.br has address 192.168.200.4

[Samba] Problems with GPO

Looking at you config setup, i noticed a few things. 

 

DC1. 

/etc/resolv.conf
domain empresa.com.br
search empresa.com.br
nameserver 192.168.200.25   (=dc1)
nameserver 192.168.200.10

 

/etc/resolv.conf
domain empresa.com.br
search empresa.com.br
nameserver 192.168.200.4   (dc=2)
nameserver 192.168.200.10

 

 

/etc/resolv.conf
domain empresa.com.br
search empresa.com.br
nameserver 192.168.200.25
nameserver 192.168.200.10

 

I suggest you change you DC resolv.conf setup first and change the following. 

 

DC1. 

nameserver 192.168.200.4

nameserver 192.168.200.25 

 

DC2

nameserver 192.168.200.25

nameserver 192.168.200.4

 

Fileserver 

nameserver 192.168.200.4

nameserver 192.168.200.25

 

 

and to make sure run this script, to check on database replication errors. 

http://downloads.van-belle.nl/samba4/samba-check-db-repl.sh 

This compaires the samba AD DC databases. ( up to 10 DC.s ) 

Its no need to configure anything in the script. 

 

And based on you config below i guessing you AD DC servers are runing backend
RID and the file server backend AD.

A mixed setup is, as far as I know not supported. 

 

Please reread :

https://wiki.samba.org/index.php/Setting_up_Samba_as_an_Active_Directory_Domain_Controller#Setting_up_the_AD_DNS_back_end

start and the second blue part after ?Provisioning a Samba Active Directory?  

..... 

However, to enable them in an existing domain requires to manually extend the AD
schema. For further details about Unix attributes in AD, see::
*	Setting up RFC2307 in AD 
*	idmap config = ad

I copied idmap.ldb from DC1 to DC2, now uidNumber and gidNumber are the same.
But in File Server is still different of the DC.

I would like to remove without reference objects in my Domain. (Ex: SID:
S-1-22-33-55 "unknown"). Is Possible ?



GPO List has still problems

    raise RuntimeError("Could not find a DC for domain", e)

In DC1 has 2 pastes in Sysvol\empresa.com.br: Policies and Scripts. But in DC2,
the Policies paste there isn't. Is this normal?

I'm using INTERNAL Samba DNS. Following my DNS tests:

root at dc1:~# host -t SRV _ldap._tcp.empresa.com.br.
_ldap._tcp.empresa.com.br has SRV record 0 100 389 dc1.empresa.com.br.

Just make it yourself a bit more easy.

Setup sysvol like this.

[sysvol]
        path = /home/samba/sysvol
        read only = No
        acl_xattr:ignore system acls = yes

Restart samba, and set the SHARE RIGHTS and File/Folder rights again.
Or atleast check them, the defaults should be ok.

When thats done.
Go here. :
http://trekker.net/archives/group-policy-downloads/
get the ADMX templates you need.

Win 10 build 1607 is not on that site, found here :
https://www.microsoft.com/en-us/download/details.aspx?id=53430

and for otheres, install this in win 7 and copy the templates to the sysvol.
( located somewhere in programfiles )

Extra usable templates here:
http://winintro.com/

now, when thats done, and this if more for you.

Does the user bacci need Domain Admin.
Like is it you replacement for user Administrator?  Then thats ok.
If its a normal user which needs todo GPO stuff. Then i suggest adding this user
to "Group Policy Creator Owners" and dont abuse the domain admin
group.

So this is the basic stuff go a GPO setup.


Now, about the error :
ERROR(runtime): uncaught exception  ...
You can ignore it IF you use the parameter : acl_xattr:ignore system acls = yes
Or, move all folder from sysvol, do the sysvol reset, and place the folders
back, that can help.

I do advice to setup GID for "Domain -" Users/Admins/Guest and most
important. "Domain Computers" .. now we are getting to you problem.

Due to all MS changes, how policies are applies has changes.

The user setting is not applied anymore by the user, but by the computer.
This is key to remember.

So for every policy you set you need one the these groups.

1) authenticated users  ( users and computer accounts ) ( preffered )
2) Domain users + any group  this is a group for applying the GPO.
3) Domain computers/ any computer group

In option 1, nothing special is needed.
In option 2, you must set read GPO polices for domain users, and read+apply for
the custom group.
In option 3, same as option 2. but this is only for a computer policie.

If you have problem like, GPO applies from one server, but the other dc.
Run : net cache flush
Stop samba on both DC's and copy the idmap.tdb from DC1 to DC2.


About you setup and config, looks all fine to me, exept.> 117, in dc_url
>     raise RuntimeError("Could not find a DC for domain", e
Please post you resolv.conf /etc/hosts /etc/nsswitch.conf
And are you using bind_DLZ or internal samba DNS

Greetz,

Louis
