Thank you for your replies, the default behavior is good, but unfortunately
not enough for my need.
You all skipped the 2nd part of my message :-)
- Is it possible to tell SSSD to dynamic DNS all eth, and add a suffix with
the ID NIC such as : server1-eth0 .test.com / server1-eth2 .test.com,
etc....*
or something like that?
myserver-eth0.domain.local
myserver-eth1.domain.local
myserver-eth2 .domain.local
or even something more customizable with
myserver.domain.local
myserver-mgt.domain.local
myserver-oob.domain.local
myserver-nas.domain.local
The idea would be to add a suffix (or prefix) to the hostname per NIC.
It is maybe a very specific need, but I could be a nice feature I think.

Hi Personne.
SSSD by default uses the address from the interface that is used when
communicating to IPA or AD.
See man sssd-ad and sssd-ipa:
dyndns_update (boolean) (this is from IPA)
....
The IP address of the IPA LDAP connection is used for the updates, if
it is
not otherwise specified by using the dyndns_iface option.
....
