Managing Users
This article provides instructions on how to manage i4scada users. It also covers topics such as user types and the available actions.
This section is dedicated to the management of users within the i4scada Studio application.
Before starting to work with the i4scada Studio User Manager, make sure that the i4scada Server is running. To start the i4scada Server open i4scada Service Manager.
i4scada Server running
The list displays all the existing project users. The list of users is split up into the following columns:
Active - if the checkbox is enabled, the listed user is active.
Type - depending on the displayed icon, listed users may be either i4scada users
or domain users 
.Name - the name of the user
Description - the description of the user
Actions - this last column is an atypical one. In the Actions column, the actual user management actions are available. The available actions for a listed user are: Clone
, Change password 
, Edit 
and Delete 
.
i4scada can accept logins from two types of users: local users (normal user) and domain users (ActiveDirectory User).
The ActiveDirectory Users can log in Ewon by HMS Networks using their Windows Domain credentials, and their properties will be partially shared between Active Directory and Ewon by HMS Networks .

Selection of the user type is done at user creation, by deciding between the two Add buttons: 
and 
. Regardless of the selected Add option, the Add dialog features the same User information fields.
Add User dialog
Following settings fields are available when adding a new User:
Name - The name of the user. This field is highlighted in red color, indicating that field is required.
Description - The custom description of the user. This field can be used to specify particular details about the user.
Authorization groups - The authorization groups field, features a multi select option that contains all available entities. This list also displays at the top right side, a select / unselect button.
Active - Enables the user to take actions in the system. If this option is not checked, the user cannot log in or perform any actions in i4scada visualizations.
Multiple logons - If active, the user is able to log on simultaneously in the same i4scada visualization from different locations.
Log activities - If enabled, all the user's login and logout actions are stored as events in the database.
Privileged writing - If enabled, it allows the user to take ownership of the write groups configured with restricted access, even if they are currently owned by another user.
Password expires - If enabled, the user's password will expire after the time period specified in the Max. Password Age option of the Password Policy dialog.
User level - Displays the level of the user. Users can be split into multiple user levels for easier management.
Auto log off interval - The log off timer for idle users. If the amount of time specified here passes while the user is idle (performs no action while logged in an i4scada visualization), the user will be logged off. When returning from the idle state, the user must log in again.
Max. failed logons - Specifies the number of failed login attempts that can be made before blocking the user. If the user tries and fails to log in more than the number of times specified here, the system will automatically block him for one minute. After the first minute, the user can try to log in again. If the next attempt fails, the user will be blocked for the next 2 minutes, and so on. For each consecutive failed login attempt, the block time will be increased to a maximum of 30 minutes. If the user performs a successful login, the failed login attempts and the block time will be reset. If the i4scada Server is stopped while a user is blocked, the user will be allowed to attempt to login directly when the Server starts. If the attempt fails, the user will be blocked again and the block time increases from the previous increment.
Failed logons - Displays the number of failed login attempts that the selected users have. This value can be reset by an Administrator.
First name - The first name of the user.
Last name - The last name of the user.
