[SSSD-users] SSSD and Dynamic DNS - clarification

Hello, In my testing it would appear for Dynamic DNS to work (update DNS A and PTR records), the Linux client hostsname needs to be FQDN (client123.domain.com) defined as one of the hostnames in /etc/hosts for the 127.0.0.1 IP as: [/etc/hosts] 127.0.0.1 client123.domain.com client123 localhost.local localhost 172.16.5.10 client123.domain.com client123 If I have something like, dynamic DNS does not appear to work: [/etc/hosts] 127.0.0.1 localhost.local localhost 172.16.5.10 client123.domain.com client123 The second /etc/hosts file should be correct but dynamic DNS is not working. Is there something in the implementation that requires the first case, or should just the order of the /etc/hosts entries modified so that the localhost appears second in the list? Frank
