My AD-admin affirms that the problem with Linux clients is -
that they recognize AD/ldap server as DNS server; they should be able to recognize
automatically the right DNS servers
Stripping sssd.conf doesn't help;
Client still chooses DNS another server from pool of ldap/ad servers, with the same
effect: non responding server for nsupdate
How can I force sssd to choose the right DNS server?
There is 'dns_discovery_domain' option, but it means thet client configuration
will differ per domain
Our AD structure is forest with trusted subdomains, and Global Catalog.
Best,
Longina

Hi
Narrow it down. Set the primary dns on your client to be a dns server
which you know for certain is handling your ad domain. For now remove
other dns entries and strip sssd of anything apart from ad.
/etc/hosts
127.0.0.1 catral.hh3.site catral localhost
/etc/resolv.conf
search hh3.site
nameserver 192.168.1.16
sssd.conf
[sssd]
services = nss, pam
config_file_version = 2
domains = hh3.site
[nss]
[pam]
[domain/hh3.site]
id_provider = ad
access_provider = ad
auth_provider = ad
ldap_id_mapping = false
e.g. here is an openSUSE client running 1.11.5 joined to the domain
hh3.site. The DC at 192.168.1.16 is also running bind for this domain.
A session on catral with a common error;)
catral:/home/steve # nsupdate -g
update delete catral.hh3.site. in A
send

code may provide more information, Minor = Ticket expired.
catral:/home/steve # kinit -kt /etc/krb5.keytab CATRAL$
catral:/home/steve # nsupdate -g
update delete catral.hh3.site. in A

catral:/home/steve # nslookup catral
Server: 192.168.1.16
Address: 192.168.1.16#53
Name: catral.hh3.site
Address: 192.168.1.25
If you haven't got the dns exactly right, you may need some tweaks in
sssd.conf to get you there:
