[Samba] Samba DC sync issues - help

Help, my Samba DC's refuse to sync :-(

I have 2 Samba 4.1.17 DC servers.  I made some changes via Active Directory
USer and Computers on Windows.  However even after a weekend the changes do
not appear on the second DC.

If I run
samba-tool ldapcmp ldap://dc1 ldap://dc2 -Uadministrator
--filter=msDS-NcType,serverState,subrefs

I see:

************************************************************

Running a manual replication seems to work fine:
samba-tool drs replicate dc2 dc1 DC=win,DC=office
Replicate from dc1 to dc2 was successful.

However nothing changes, when I do an ldapcmp I still see the same errors.
What am I doing wrong? (Note: the clocks are synchronised)  I've been
trying to solve this for a week now but I cannot figure out what is going
wrong.

[Samba] Samba DC sync issues - help

Hai, 

Reboot both servers first, DC1 and wait until its fully up, then reboot DC2, and
run the replicate again but now like this :

samba-tool drs replicate dc_WITH_FSMO_ROLES dc_TO_SYNC_TO DC=win,DC=office

report if this worked. 

And check with this one, you can run it on any samba DC.
https://secure.bazuin.nl/scripts/samba-check-db-repl.sh 

configure it, and run it, and report back.
For the configure, NT_ADMIN_USER/PASS is sufficient. 
And set CONFIGURED to yes 


Greetz, 

Louis

[Samba] Samba DC sync issues - help

Hello Nico, 

 

Your completely right, sorry about that. 

 

samba-tool drs replicate dc_2_REPLICATE2  SOURCE  DC=win,DC=office

 

and if needed you can try one of the options 

--full-sync

 

Still errors after a reboot?  

 

 

Greetz, 

 

Louis

Hi Louis,


just to make sure I'm not going to overwrite my working dc with the one
which is out of sync:

    samba-tool drs replicate dc_WITH_FSMO_ROLES dc_TO_SYNC_TO DC=win,DC=office


according to the man page the first dc is the destination, the second is the
source. In my case that would mean syncing from dc2 to dc1.  Is that really what
I should do as dc2 is the one which is out of sync.


Nico

[Samba] Samba DC sync issues - help

Hi Louis,

Rebooted DC1
Rebooted DC2
Ran "samba-tool drs replicate dc1 dc2 DC=win,DC=office"
Replicate from dc2 to dc1 was successful.

Unfortunately samba-check-db-repl.sh seems to be hanging when doing 'kinit
Administrator ' (if seems ' echo"pwd" | kinit
Administrator' doesn't seem
to manage to pass on the password for some reason)
However when I now run an ldapcmp I see success everywhere.  When I update
something via Windows and run ldapcmp afterwards everything is still ok.

So either the reboot of dc1 fixed it (I didn't try that before as it was
the one running my whole network as dc2 was down) or the reverse replicate
fixed it (am I totaly misunderstaning 'samba-tool drs replcate destination
source' or is the manual wrong?)

Thank you very much for your help!

Nico

[Samba] Samba DC sync issues - help

Hai Nico, 

 

Ok great, its fixed, and yes, i do think that the reboot fixed it, dont ask my
why, i dont know.. i only know the fix ;-)

Seen this few times before.. 

 

About the script, did you run it without the password in the script or with the
password in the script?

So i can check whats wrong there. 

 

Your running samba 4.1.17 ? on which os? 

 

Greetz, 

 

Louis
