Configuration Files and the nfsmapid Daemon

The nfsmapid daemon uses the SMF configuration information found in svc:system/name-service/switch and in svc:/network/dns/client as follows:

  • nfsmapid uses standard C library functions to request password and group information from back-end name services. These name services are controlled by the settings in the svc:system/name-service/switch SMF service. Any changes to the service properties affect nfsmapid operations. For more information about the svc:system/name-service/switch SMF service, see the nsswitch.conf(5) man page.

  • To ensure that NFS Version 4 clients are capable of mounting file systems from different domains, nfsmapid relies on the configuration of the DNS TXT resource record (RR), _nfsv4idmapdomain. For more information about configuring the _nfsv4idmapdomain resource record, see nfsmapid and DNS TXT Records. Also, note the following:

    • The DNS TXT RR should be explicitly configured on the DNS server with the desired domain information.

    • The svc:system/name-service/switch SMF service should be configured to enable the resolver to find the DNS server and search the TXT records for client and server NFS Version 4 domains.
