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.
