Hi jlliagre, MadeInGermany,

Yea.. thanks for your advices.

That's precisely where I am confused. The use of this DNS client service. Seems pretty redundant ?

I am thinking if this is turn on, maybe DNS caching will take place ?

	      The password to be used by the Directory Server for the Directory Manager user

       -d, --debug
	      Enable debug logging when more verbose output is needed

       --ip-address=IP_ADDRESS
	      The IP address of the IPA server. If not provided then this is determined based on the hostname of the server.

       --forwarder=FORWARDER
	      A  forwarder  is a DNS server where queries for a specific non-resolvable address can be directed. To define multiple forwarders use
	      multiple instances of --forwarder

	      Do not add any DNS forwarders, send non-resolvable addresses to the DNS root servers.

       --reverse-zone=REVERSE_ZONE
	      The reverse DNS zone to use

       --no-reverse
	      Do not create new reverse DNS zone. If used on a replica and a reverse DNS zone already exists for the subnet, it will be used.
