I'm migrating from a legacy NIS setup to ipa. I have a number of NIS

I've create a new netgroup in ipa (for testing) and added some hosts to it
(using ipa netgroup-add and ipa netgroup-add-member). I'm hoping that when
exporting an nfs share using the @netgroup syntax in /etc/exports that the
netgroup will be looked up in ipa and the share will be exported to the
hosts in the netgroup.
/etc/nsswitch.conf has a line:
netgroup: files nis sss
/etc/exports has a line:
I haven't, so far, been able to mount the exported share on a client so I'm
wondering if this setup would be expected to work?
What is confusing to me is that the section in the Redhat 6 Identity
Management guide on netgroups also has information on running the NIS
listener plugin so I'm wondering if perhaps this only works when running the
nis listener. I'm trying to avoid that.
I'd welcome any clarification on how to do non-kerberised nfs exports to
groups of hosts.
Does getent netgroup rmjnetgroup1 show the hosts you'd expect?
Indeed it does.
The individual triples listed for the netgroup contain entries like:
where host is a fully qualified hostname which is dns resolvable.
(For info if I do ypcat on one of my NIS netgroups I get a triple like this:
where host is the fully qualified host name, and nothing in the domain
I've actually tried two netgroups with different domains set. The first
one (rmjnetgroup) I made without specifying the --nisdomain option to
ipa netgroup-add and domain in the output above shows as my dns domain
(which is a lower case version of my kerberos realm).
I couldn't mount nfs shares when exporting to @rmjnetgroup. I checked
that I could mount the shares when I exported explicitly to the fully
qualified host name, and that worked ok.
So, thinking that the problem was with the domain name I made a new
netgroup (rmjnetgroup1) with the option --nisdomain=xxx where xxx is the
proper name for our nis domain as shown with the domainname command.
I couldn't mount nfs shares when exporting to @rmjnetgroup1 either.
