The document that needs to be completed with the customer to collect configuration items such as IP addresses, Gateway, DNS servers, and NTP Servers is the Technical Checklist. This checklist is designed to ensure all necessary technical information is gathered prior to the installation, enabling a smooth and efficient setup process.References: Nutanix Cluster Deployment Guide, Pre-installation Planning Documentation.

In a Nutanix environment, if the login process using an Active Directory (AD) user account takes more than a minute to complete, it could be due to the configuration of the AD lookups.
Active Directory lookups can be configured to use either Recursive or Non-Recursive mode. In Recursive mode, the system will look up each group that a user is a member of, then each group that those groups are members of, and so on. This can lead to a large number of lookups and potentially slow down the login process1.
On the other hand, in Non-Recursive mode, the system only looks up the direct groups that a user is a member of. This can significantly reduce the number of lookups and speed up the login process1.
Therefore, the administrator should confirm that Active Directory lookups are configured to use Non-Recursive mode to resolve this issue.
