What are some considerations when planning to use NFS Kerberos?

When planning to use NFS with Kerberos authentication, it's essential to consider how user accounts across different hosts interact with the NFS shares. Specifically, the correct choice highlights the issue that utilizing different Active Directory users on various hosts to access the same NFS share can lead to vSphere vMotion migration failures.

In a vSphere environment using NFS, vMotion requires that the source and destination ESXi hosts have a seamless transition, which includes ensuring that the authentication and permissions for accessing the NFS share are consistent. If different users are utilized across these hosts when accessing the same NFS share, it can disrupt the authentication process during the migration, ultimately leading to failed operations.

Establishing uniformity in user accounts across participating hosts aligns with the requirements for a successful authentication mechanism in a Kerberos-enabled environment, as Kerberos relies on proper identification of users and their associated permissions across different systems. Thus, managing user accounts properly is crucial for maintaining functionality and operational integrity while using NFS Kerberos.
