How to get list of the all active user details in the environment

In designer People tab, it will display all active user lists (by default). For deactivate users, you need to click on ‘View deactivated user’ link (marked in screen).
To know user’s group click on users name or open user’s profile and then click on user’s group option. (Refer attached screens)

Thanks Amit. I know but I need to put these details in the report. Is there any function which can provide me the list

Its kind of Audit report.

Have a look at the following plugins which may help with users and their group memberships.

For login details you will need to combine this with the login-audit.csv file in your logs directory.
Also have a look at the following, it doesn't seem to have been updated for recent versions however

Thanks Tim, Is there any way without the plugin we can get the list of all the active user to put it in a report I am creating an Audit tempo report where I have to put the user details first name last name username which group they belong and when is the last time they logged in.

Not that I can think of, the various plugins I've mentioned were created because what you're attempting isn't easy OOTB. You will need a good level of process and expression experience to do it. Maybe someone else in your organisation can help with that.

OK Tim, I will check the plugin. Could you also let me know if there are any Database tabled which contain these People Information where we can query?

Since you're talking about group membership that is not necessarily associated with Tempo then there's no database table where you can extract this from.

This is another Shared Component that can help with the Users and Groups report "Appian Users and Group Membership" forum.appian.com/.../summary
