The Sanity tab allows you to generate reports useful for maintaining a clean Jira environment.
Last Login
The Last Login report shows all users who have not logged in before a specified date. This helps keep track of inactive users that still count toward your license limit.
You can deactivate (remove user from all the groups he/she belongs to and remove him/her from any project roles he/she might have) and delete (remove user from Jira) users. To do that check the users you want to deactivate/delete.
To select all users click the checkbox from the User column.
On Delete Users a box is displayed to confirm if you want to continue with this action.
Starting with version 2.6.3 deactivating a user just sets its active flag to false, keeping its associated groups and project roles.
In case of users from read-only LDAP directory, for which the active flag can't be updated, they are only removed from all groups associated to the following global permissions: Jira Users, Administrators and System Administrators.
Duplicate Users
The Duplicate Users report shows the users who can be found in multiple directories.
The report is aware of the mirrored user directories from the Configuration page. This means that users who only belong to pairs of directories which are already configured are ignored from the report.
The Duplicate Users report is helpful because the users shown might not belong to the same groups in both directories and if the primary crashes, those users might end up having different permissions than expected.
Deactivated Users
The Deactivated Users report shows the users who do not belong to any group nor do they have any roles on any projects. Deactivated users will not be able to log in and will not count towards your license limit. The report shows deactivated users from the specified directory.
You can activate (add user as member of a group - only groups who have Jira User permission) and delete (remove user from Jira) users. To do that you have to check the users you want to activate/delete.
To select all users click the checkbox from the User column.
To Activate Users, a dialog will be displayed from where you can choose the groups to add the selected users to.
To Delete Users a dialog will be displayed to confirm the action.
Starting with version 2.6.3, activating a user which has its active flag set to false just sets it back to true, preserving the user's associated groups.
In case of users which have the active flag set to true, but aren't members of any of the groups associated to the following global permissions: Jira Users, Administrators or System Administrators, they will be added to the selected groups from the Jira Users Groups dialog.
