The default password expiry for the machine account used to integrate Nutanix Files with Active Directory is 0 days , meaning the password does not expire by default. When Nutanix Files is integrated with Active Directory (AD) for authentication and authorization, a machine account is created in AD to facilitate communication between the Nutanix Files file server and the AD domain. This machine account is used for tasks such as SMB share authentication and permission management.

According to the Nutanix Unified Storage Administration (NUSA) course, “The machine account created for Nutanix Files integration with Active Directory has a default password expiry of 0 days, meaning the password does not expire unless explicitly configured in the AD policy.” This ensures that the integration remains stable without requiring frequent password updates, which could disrupt file share access.

The Nutanix Certified Professional - Unified Storage (NCP-US) study guide confirms that “Nutanix Files machine accounts are configured with a non-expiring password (0 days) by default to maintain continuous AD integration.” However, administrators can override this by applying a custom AD group policy to enforce password expiry, but this is not the default behavior.

The other options (30 days, 60 days, 90 days) do not reflect the default setting for Nutanix Files machine accounts, as the system is designed to avoid automatic password expiry to ensure uninterrupted operation.
