Authentication considerations for NFSv4 based access

Authentication considerations for NFSv4 based access are as follows.

NFSv4 username-mapping configuration
  1. To enable NFSv4 access, the NFS server username-mapping configuration on IBM Storage Scale must be updated.
    mmnfs config change "IDMAPD_DOMAIN=myDomain.com"
  2. On an NFS client, ID map configuration must also be updated to reflect the same domain name as defined on an NFS server. Additionally ID-mapping service must be started.
    For example, on RHEL 7.x NFS clients:
    • The ID map configuration file name is etc/idmapd.conf. Update the domain attribute in the file to reflect the domain name that is defined on the NFS server.
    • Start nfs.idmap service.
    Note: The ID map configuration file and the ID-mapping service can be different on various OS platforms.
