...(Samba 4.5.16) which I've deployed as a soon-to-be replacement. All credentials are valid as I can log in to the domain with both. Both accounts, as far as I can tell, look identical from AD perspective. The only difference that I can spot is when I run "ldapsearch -D 'account at matrixscience.co.uk' -b 'cn=Users,dc=matrixscience,dc=co,dc=uk' -H ldap://dc15 -W sAMAccountName=account" The responses are successful and identical apart from these 2 lines: msDS-SupportedEncryptionTypes: 0 msSFU30Name: account2 which only appear for the second (problematic) account.

Hi all, I have an old dc (4.0.9). Let's call it dc1. I also have a new one (4.5.16) which I'm planning to switch to. Let's call it dc2. After initial set up of dc2 I initialised replication and things looked ok for a couple of weeks. Recently I've managed to mess it up. Possibly by editing users and DNS records. Or copying Kerberos cache and trying to use it elsewhere for

pfSense DHCP integration with Samba AD DDNS

pfSense DHCP integration with Samba AD DDNS
That's helpful. About half of our DHCP clients are Unixes. Maybe I'll find a way to make pfSense perform a Kerberos handshake with Samba for the sake of updating DNS. If not, I'll just install isc-dhcp-server on the Debian container running Samba AD.

LDAP authentication logging
Hi all, I'm running old Sernet samba 4.0.9 on Debian and trying to set up LDAP authentication for https://www.reviewboard.org/docs/manual/3.0/admin/configuration/authentication-settings/ To cut a long story short about half of users can log in and half not without any obvious reasons that ldapsearch comparisons would reveal. So I really want to see what the server is saying. I've

pfSense DHCP integration with Samba AD DDNS
Hi Rowland, I don't want to to run an AD DC on firewall device, barely DHCP and maybe DNS. What you have pointed me to is similar to what I have in place: https://blog.michael.kuron-germany.de/2011/02/isc-dhcpd-dynamic-dns-updates-against-secure-microsoft-dns/ and which is working fine. NOW I want to switch DHCP from isc-dhcp-server 4.2.2 on Debian to DHCP on pfSense firewall (based on

On dc1 port 53 is mapped to /usr/sbin/named -u bind. On dc2 it's /usr/sbin/samba. I wasn't sure what to do when I deployed dc2. I remember installing bind9 on dc2 but then purging it.

Hi Rowland, I've decided to roll back samba on DC1 to the state from a couple of weeks ago, before I started all this mess... Since the email subject change :) Stopped bind9 and sernet-samba-ad and copied /var/lib/samba aside. Restored samba folder from backup, started sernet-samba-ad but bind9 fails to start: Jul 22 14:39:39 dc1 named[27846]: generating session key for dynamic DNS Jul
