Configuring Access Appliance for ID mapping for NFS version 4
If you plan to use NFS version 4, you must configure Access Appliance to map the user IDs to the required format. In NFS version 3, each user is identified by a number, the user ID (uid). A UNIX file also identifies the owner of the file by a uid number. NFS version 4 has a different way of identifying users than that used by NFS version 3. In NFS version 4, each user is identified by a string, such as user1@example.com.
Access Appliance requires a mechanism to map the user strings from NFS version 4 to uids on the server and the client. This process, called ID mapping, uses a file /etc/idmapd.conf.
NFS version 4 uses the /etc/idmapd.conf file to map the IDs. The Domain field needs to be set to the DNS domain of the Access Appliance server. If the DNS domain is not set, the ID mapping maps all of the users on the client to the user 'nobody'.
To configure Access Appliance for ID mapping
- Configure the DNS domain of Access Appliance using the following command:
Network> dns set domainname domainname
When the NFS server is started, the
/etc/idmapd.conffile is updated with the domain information of the Access Appliance server.
You must also configure the NFS client.
