[Samba] Error join samba 4.10.7 to samba 4.4.5

Hi,

After reading wiki documentation about join I have tested to join a
second dc, but with problems.

I need to add a second controller to our AD, and then upgrade existing
server (4.4.5)  and I have tried to join a new DC 4.10.7 to 4.4.5
server but I receive join errors, attached output  wit and without
debug:
I have executed samba-tool dbcheck --cross-ncs all seems OK

I have made a test upgrading actual 4.4.5 to 4.10.7 and then join
4.10.7 to update DC to 4.10.7 and then works, bu first I need to add a
second controller to ensure no downtime.

some questions:
1) Why I receive this error?
Replicating critical objects from the base DN of the domain
Partition[DC=DOMAIN-TEST,DC=com] objects[98/98] linked_values[762/0]
Missing parent while attempting to apply records: No parent with GUID

ps,DC=DOMAIN-TEST,DC=com
Failed to commit objects: WERR_DS_DRA_MISSING_PARENT

--> not sure if can be related with this issue:
https://bugzilla.samba.org/show_bug.cgi?id=13274

2) About join in wiki appears
"
If the other DCs are Samba DCs and were provisioned with
--use-rfc2307, you Should add --option='idmap_ldb:use rfc2307 = yes'
to the join command
"

But checking my command userv to migrate from samba nt doamin to our
actual ADDC domain this command was not used, but checking smb.conf
appears this:
 idmap_ldb:use rfc2307 = yes

But I'm not sure if I have to use --option='idmap_ldb:use rfc2307
yes' on join command

cleaning up deleted objects would remove this.

The second is where it falls apart:

First, is it actually 'OU=Grups' ? or is it 'OU=Groups' ? (I had
to
stitch your output together, but I am sure the 'o' wasn't there)

Second, does the GUID 'cdee5b31-365d-4c8f-9368-4115b6307a19' exist in AD
or has it been deleted ?

Third, why move 'Domain Users' from
'CN=Users,DC=DOMAIN-TEST,DC=COM' ?

Not that issue, but a very well known one.

The trouble is, Samba 4.4 was happy to get a tree like this:

 X
| |
Y Z

in an order like this:

Step 1

Y

Step 2

Y Z

Step 3
 X
| |
Y Z

As long as everything worked out in the end, it was fine.  But this had
issues, so we patched it to instead demand the objects in tree order
(GET_ANC), but of course the server needs to know what that means. 

Samba 4.5 was, from memory, the first release we did that, but the
server, even with 4.4, didn't really know what that flag meant.  

It wasn't until much later, Samba 4.6 or so, when we finally got the
flag right, which of course gives problems upgrading from Samba 4.4.
(We would sort the current 'page' of replication entries, but not the
whole partition).

We have continued to improve this code since, but that is the core. 
The next issue is a flag called GET_TGT but that hurts much less often,
as we have a client-side workaround detecting that the server didn't
understand us. 

The workaround for you is to carefully touch each object such that the
children are modified after the parents.  Or upgrade in-place that DC
and replicate from there.  Both suck, I know.

Probably.  But that isn't the big deal at this point. 

I hope this helps a little.  We need to extend our wiki to explain this
more I'm sure.

I've CC'ed samba-technical for those there who might want to learn the
history a bit more.

[Samba] Error join samba 4.10.7 to samba 4.4.5

Hi,

Thanks, I'll try to answer your questions:


You seem to have two errors, the first:

Missing target while attempting to apply records: Deleted target CN=NTDS
Settings\0ADEL:193acd86-264a-462a-87aa-a4948f35c908,CN=DC2\0ADEL:c6bef0f5-e4cb-42d4-baf2-ae344091d09b,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=domain-test,DC=com
GUID 193acd86-264a-462a-87aa-a4948f35c908 linked from
CN=7ac4d0d7-beb3-4f47-b192-9b4e2547f787,CN=Partitions,CN=Configuration,DC=DOMAIN-TEST,DC=com

--> How can I know what object is this?

Is referring to a deleted object and as such isn't really a problem, but
cleaning up deleted objects would remove this.

The second is where it falls apart:

Missing parent while attempting to apply records: No parent with GUID
cdee5b31-365d-4c8f-9368-4115b6307a19 found for object remotely known as
CN=Domain Users,OU=Grups,DC=DOMAIN-TEST,DC=com
Failed to commit objects: WERR_DS_DRA_MISSING_PARENT

First, is it actually 'OU=Grups' ? or is it 'OU=Groups' ? (I had
to
stitch your output together, but I am sure the 'o' wasn't there)

--> IS a ou created to move ou new groups and also domain users group

Second, does the GUID 'cdee5b31-365d-4c8f-9368-4115b6307a19' exist in AD
or has it been deleted ?

--> How can I know what is this objects, where I can find this guid
and real name?

Third, why move 'Domain Users' from
'CN=Users,DC=DOMAIN-TEST,DC=COM' ?

--> was moved to our new ou to organize, I'll try to test moving to
Users and I'll reports the results

thanks!!!

[Samba] Samba 4.4 AD DC and GET_ANC restriction from Samba 4.5 DC joining (was: Re: Error join samba 4.10.7 to samba 4.4.5)

Hi Andrew,

thanks for you information, but I have some question, I'm not a samba
expert... Sorry!

Not that issue, but a very well known one.

The trouble is, Samba 4.4 was happy to get a tree like this:


 X
| |
Y Z

in an order like this:

Step 1

Y

Step 2

Y Z

Step 3
 X
| |
Y Z

As long as everything worked out in the end, it was fine.  But this had
issues, so we patched it to instead demand the objects in tree order
(GET_ANC), but of course the server needs to know what that means.

Samba 4.5 was, from memory, the first release we did that, but the
server, even with 4.4, didn't really know what that flag meant.

It wasn't until much later, Samba 4.6 or so, when we finally got the
flag right, which of course gives problems upgrading from Samba 4.4.
(We would sort the current 'page' of replication entries, but not the
whole partition).

We have continued to improve this code since, but that is the core.
The next issue is a flag called GET_TGT but that hurts much less often,
as we have a client-side workaround detecting that the server didn't
understand us.

The workaround for you is to carefully touch each object such that the
children are modified after the parents.  Or upgrade in-place that DC
and replicate from there.  Both suck, I know.

--> Not really sure where is the issue, but moved domain users to
CN=Users and now join from 4.10.7 to 4.4.5 and seems to work!! Great!!
 Thanks!!!
During join some errors "duplciate value attribute CN=.." but I can
find what is duplicated, and some values that appears as duplciated
are not showed on RSAT tools,  any suggestion how to solve this
issues?


RFC2307, It seems that join has not added, I'll try to add manually
and also add some other config that are not added cert config


Thanks
