rpc.idmapd configuration file is usually found at /etc/idmapd.conf. See idmapd.conf(5) for more information.
In section "[Translation]", modify/set "Method" attribute to contain sss.
In order to change the default of one of the configuration attributes of the sss plugin listed below you will need to create a config section for it, named "[sss]".
Configuration attributes
memcache (bool)
Default: True
The sss plugin requires the NSS Responder to be enabled in sssd.
The attribute "use_fully_qualified_names" must be enabled on all domains (NFSv4 clients expect a fully qualified name to be sent on the wire).
The following example shows a minimal idmapd.conf which makes use of the sss plugin.
[General] Verbosity = 2 # domain must be synced between NFSv4 server and clients # Solaris/Illumos/AIX use "localdomain" as default! Domain = default [Mapping] Nobody-User = nfsnobody Nobody-Group = nfsnobody [Translation] Method = sss
