This article helps with steps to delete existing user from PAA.

Also if the user delete is stuck then how to forcefully delete the user from backend CLI.

Recommended way to delete or remove any user from WebUI access is to remove them from the User list.

From WebUI -> Under Account > Permissions : you can manage users associated with a Paragon Active Assurance account, and their privileges. You can invite new users, remove users, and change permissions for each user individually.

If the user is removed but still seen under User list then follow below steps to forcefully remove the user -

root@ubuntu18044amd64:~# ncc user-delete [email protected] –force

WARNING! This will remove all related objects for the user [email protected]. You cannot reverse this!

(Use --quiet to supress this prompt)

Please enter the e-mail of the user again to delete it: [email protected]

Removing user [email protected] and all related objects
