[Samba] Unable to browse system shares of a newly migrated AD DC

I think this wont work since the user connectig isnt known in the AD,
since the user connecting is mapped to user nobody. 


auth_check_password_send: Checking password for unmapped user []\[]@[]
auth_check_password_send: mapped user is: [CCENTER]\[]@[]
connect_acl_xattr: setting 'inherit acls = true' 'dos filemode =
true'
connect to service IPC$ initially as user NT AUTHORITY\ANONYMOUS LOGON
(uid=65534, gid=3000009)
and 'force unknown acl user = true' for service IPC$

cat /etc/passwd | grep nobody
nobody:x:65534:65534:nobody:/nonexistent:/bin/sh

and by default "Guest" (nobody) is disabled in the AD. 



Greetz, 

Louis

Hi Louis, It works for me

This appears in log.smbd on my DC when I run the same command:

[2015/03/30 10:15:42.442881,  3] 
../source3/smbd/service.c:856(make_connection_snum)
   dc01 (ipv6:::1:43602) connect to service IPC$ initially as user NT 
AUTHORITY\ANONYMOUS LOGON (uid=65534, gid=3000013) (pid 16566)

3000013 on my DC is SID S-1-1-0, which is 'Everyone'

So the questions are, what are the permissions on /tmp and is user 
'3000009' on the DC 'Everyone'

[Samba] Unable to browse system shares of a newly migrated AD DC

I've never got this to work ok with "Guest" users.

I'll watch the thread... if you manage to get this working.

Hi Louis, If I run 'smbclient -L localhost -U%' on the DC, I get this:

root at dc01:~# smbclient -L localhost -U%
Domain=[EXAMPLE] OS=[Unix] Server=[Samba 4.1.17-Debian]

     Sharename       Type      Comment

     sysvol          Disk
     testshare       Disk

If I then run virtually the same command an a client (replacing 
'localhost' with the DCs name), I get:

Permissions are fine, but migration did not create "Users" group in
AD.
How can I resolve it?
