This is where users are maintained.

Users have a login ID, name and password.

They may also be assigned to a group here.

Note a user - "admin" - is automatically created by DataPA and cannot be deleted. The initial password for this user is "admin". Similarly an "Administrators" group, which has full permissions and cannot be removed is also created. The admin user is automatically configured as a member of this group and this cannot be changed.

The idea of having an admin user belonging to the administrator group which cannot be removed is to make it impossible to get into a situation where the security setup can no longer be maintained.

Although the admin user cannot be removed, the admin password can be changed to prevent other users accessing the account.
