This test reports the status of user accounts configured in the Active Directory server and thus, quickly points you to ‘unused’ accounts that can be deleted to make room for those that are actively used.

Measurement	Description	Measurement Unit	Interpretation
Never_loggedon_users	Indicates the indicates the number of AD users who have never logged on to the network.	Number	A healthy AD server is one that has no or very few ‘unused’ user accounts. A high value is therefore not desired for this measure. To know who these users are, use the detailed diagnosis of this measure.
Inactive_users	Indicates the number of users who are currently inactive in the AD server.	Number	To identify the inactive users, use the detailed diagnosis of this measure. The detailed diagnosis displays the Distinguished Name of the user, the date/time he/she logged in last, and the date/time at which the user account was created. This will help you in figuring out how long that user has been inactive. If you think that the user will never again become active, you can proceed to delete that user account.
Disabled_users	Indicates the number of user accounts that are currently disabled on the AD server.	Number	To identify the disabled users, use the detailed diagnosis of this measure. The detailed diagnosis displays the Distinguished Name of the user and the date/time at which the user account was created. This will help you in figuring out how long each user account has remained disabled. If you think that the user will never again become active, you can proceed to delete that user account.
