[Samba] Joining a Windows Server 2008 R2 to existing Samba4 domain

Hi Marc,

Thanks for your reply.

We are using BIND9_DLZ currently as the DNS backend

I manually selected a replication partner (the FSMO roles DC).

We do have some errors when doing a dbcheck but I'm not able to fix them.
I've detailed this in another post.

Here is an example of each type:

Example1:
*ERROR: incorrect GUID component for member in object
CN=examplegroup,OU=Groups,DC=example,DC=internal,DC=com -
<GUID=77ad92b5ade70e449dcc481624928310>;<RMD_ADDTIME=130393476680000000>;<RMD_CHANGETIME=130976799640000000>;<RMD_FLAGS=1>;<RMD_INVOCID=98307faefea70749933e6946b1b14420>;<RMD_LOCAL_USN=1445979>;<RMD_ORIGINATING_USN=303848>;<RMD_VERSION=1>;<SID=010500000000000515000000e8e83f391df4408a63c6a6b4d25a0000>;CN=simon.test,CN=Users,DC=example,DC=internal,DC=com*

Example2:
*ERROR: incorrect DN string component for member in object
CN=admin-group-001,OU=Groups,DC=example,DC=internal,DC=com -
<GUID=38370cfc-6751-49bb-945e-d2b5e028f0f3>;<RMD_ADDTIME=130941544260000000>;<RMD_CHANGETIME=130941560040000000>;<RMD_FLAGS=1>;<RMD_INVOCID=a65d0f39-311e-4031-aa56-a8585bfc1b8f>;<RMD_LOCAL_USN=1443123>;<RMD_ORIGINATING_USN=1443123>;<RMD_VERSION=1>;<SID=S-1-5-21-960489704-2319512605-3030828643-1219569>;CN=user.test,OU=Test
OU,DC=example,DC=internal,DC=com*

Example3:
*unable to find object for DN
CN=test.user2,CN=Users,DC=example,DC=internal,DC=com - (No such Base DN:
CN=test.user2,CN=Users,DC=example,DC=internal,DC=com)*
*Not removing dangling forward link*

I have edited these entries to maintain anonymity.

Any ideas on how to remove these errors?

Thanks again,
Chris.

There appears to be a bug report for this:

https://bugzilla.samba.org/show_bug.cgi?id=12297

The last comment on that is:

We're hoping to backport this soon. But before all that, can you please
patch dbcheck and run it to confirm you see a new error message ('Try
running "samba-tool domain tombstones expunge"')?

Hi Marc,

Unfortunately, I have around 600 of these errors.

I've tested manually deleting an offending entry using ldbedit -H and the
subsequent dbcheck test goes down by 1 so this would suggest that I can fix
it this way... although not sure if this is:

a. A good idea
b: The best way to fix this.

Any pointers most welcome.

Thanks,
Chris.

Further to what I posted last time, to get the tombstone expunge
command, you will need domain.py from git.

Hi Rowland,

Just saw your message on the lists about adding a tombstone command by
using domain.py.

I appear to have domain.py
in /usr/local/samba/lib/python2.7/site-packages/samba/netcmd, do I need to
do something to activate this?

Thanks,
Chris.
