How to set up NFSv4 encryption with Kerberos

NFSv4 with Kerberos encryption is a well-known and secure method of accessing Network File System version 4 file servers. When we combine NFSv4 with Kerberos, it results in secure access to file servers over the network.

Furthermore, Kerberos is a secure authentication protocol that offers secure authentication and encryption over a network. In fact, using Kerberos with NFSv4 ensures that the transmitted data transmitted is encrypted and protected from any form of unauthorized access or tampering.

Today, we are going to take a look at configuring an NFS service with Kerberos authentication. Before we begin, ensure time is synced on all servers as the Kerberos authentication method relies on time sync between servers.

1. First, we have to ensure ntpd service is running and then sync time with the AD.
2. Next, we have to ensure the smb.conf file looks like the code below if we are using the AD as the Kerberos server:

   
3. Similarly, we have to ensure the krb5.conf file looks like this:

   
4. Next, we have to ensure the required packages are installed for the NFS server and NFS client.
5. After that, we have to verify that ‘SECURE_NFS=“yes”’ is configured in file ‘/etc/sysconfig/nfs’.
6. Then, we have to configure the exports for the Server and the client.

   According to our experts, we have to ensure the last principle generated is the root principle.
7. Finally, we can test if we can access the host ticket.
