Use of specific DCs within smb.conf
Is it possible to specify a list of DCs for Samba to use, rather than have it look them up dynamically via DNS? I have an issue with Kerberos, Samba, and SSSD where my machines stop authenticating after a period of time – preAuthentication errors, etc. I suspect it's because of a "DC mismatch" between the three. Because we have numerous DCs all over the world, I specifically

You believe that SSSD is bypassing Samba entirely and going direct to Kerberos? That’s possible. At the moment, to the best of my understanding, Samba is only being used to join the domain. There are no file/printer/etc. shares happening; this is just basic domain join/membership and keytab generation and after that it’s done. The question was still specific to Samba itself: can I specify the DCs

I found adcli a little too late; I plan to use it in the future but for the time being I just deployed 16 VMs using Samba so we’re going to keep that for now! Also, the rest of what I wrote can be disregarded – I figured out exactly why my hosts were failing to authenticate after a period of time. It’s too stupid to admit publicly.

Thanks for the suggestion Rowland, I had already tried that though and both secondary DC's resolve.... host -t CNAME fbce444a-8707-4c69-8066-d75aacfb07f0._msdcs.mydomain.com. fbce444a-8707-4c69-8066-d75aacfb07f0._msdcs.mydomain.com is an alias for dc02.mydomain.com. host -t CNAME 04225dbe-d69c-4ea5-8930-eb8746790180._msdcs.mydomain.com.

dbtool --cross-ncs and undeletable errors..
Hi All, On my two-DC setup (dc00 and dc01 - Used to be a 4-Dc setup but 02 and 03 are gone), I've noticed the following errors which I am unable to fix.. Any hints? * Basic dbcheck is clean. [root at dc00 ~]# samba-tool dbcheck Checking 327 objects Checked 327 objects (0 errors) * Cross-NCS shows two errors related to a de-comissionned DC (dc02) and cannot auto-fix this.. How do I fix

Trouble demoting DC with broken replication
Hi all, I am currently struggling to remove one of our Samba4 DC from the domain. Some time ago, adding a new Samba DC to our AD did not succeed and I had to demote the new server again. After removal, replication on one of the old/existing DCs got weird. /usr/local/samba/bin/samba-tool drs showrepl gives the following: Standardname-des-ersten-Standorts\dc02 DSA Options: 0x00000001 DSA object

BIND9.8 DLZ performance issue
Hello, I'm running Samba 4.5.0 and bind-9.8.2-0.47.rc1.el6_8.1. One DC of four, the PDC, is magnitudes slower running /usr/local/samba/sbin/samba_dnsupdate --verbose --all-names. When that is running on that DC it seems to block any queries. The load average is usually under 0.5. The DC was unsafely halted, which could have corrupted something. I ran a dbcheck with samba-tool and it

4.2.2 as AD with 2 DCs: database incoherency
Hi all, I'm having a test AD domain composed with 2 DC, using Sernet's version of Samba 4.2.2. These two DC are Centos 6.6 (dc20) and Debian 7.8 (dc00). These two are using TDB as a backend (as we have no other choice at this stage of Samba's development). *dc20*:~# ldbsearch -H $sam '(objectclass=group)' dn | tail -3 # returned 27392 records # *27389* entries # 3 referrals

This doesn't really answer your question, but it already looks like you're using SSSD for authentication, and specifying local DC's (instead of DNS lookups). Why not bind to AD directly with that?
