Hi,
I've a problem with the dynamic dns updates. It seems they won't work.
Most of my clients have a dynmaic IP so sometimes they change. If I do a ping to the name, it tries do ping the old ip insead of the changed new one.
I tried a "samba_dnsupdate --verbose" and got a looking/checking output and at least a "No DNS updates needed". But the client still has the old dns-record
We've changed our setup from winbind to sssd some month ago. I'm not sure if this was working before we switched.
My setup is:
Linux Debian 4.9.168
Samba vers 4.5.16
sssd vers 1.15.0
isc dhcp vers. 4.3.5
smb.conf:
[global]
netbios name = PDC
realm = COMPANY.COM
workgroup = COMPANY
server role = active directory domain controller
interfaces = br0 tun0
idmap_ldb:use rfc2307 = yes
template shell = /bin/bash
template homedir= /home/%U
dns forwarder = 8.8.8.8
ldap server require strong auth = no
log file = /var/log/samba/log.samba-ad
max log size = 10000
log level = 2
domain logons = Yes
panic action = /var/lib/samba/gdb_backtrace %d
mangled names = no
unix extensions = no
acl allow execute always = True
follow symlinks = yes
wide links = yes
sssd.conf:
[sssd]
config_file_version = 2
services = nss, pam
domains = COMPANY.COM
[domain/COMPANY.COM]
id_provider = ad
access_provider = ad
sudo_provider = none
ldap_id_mapping = false
fallback_homedir = /home/%u
default_shell = /bin/bash
skel_dir = /etc/skel
krb5_keytab=/etc/krb5.sssd.keytab
enumerate = true
ldap_user_gecos = description
cache_credentials = false
ldap_enumeration_refresh_timeout = 30
If you need some more infos please let me know but I think I just missed an option to activate it?
