Concurrent logins can lead to the use of valid credentials by illegitimate personnel at the same time as the legitimate user to authenticate to the network. This could lead to multiple security issues within the organization like misuse of the user's personal information or resources to perform unauthorized actions. This can also result in the user being wrongly held accountable for the harmful actions of another user with malicious intent.
In ADSelfService Plus, when a user is logged in from multiple clients, it increases the chances of credentials being misused to perform illegitimate password self-service operations. Additionally, they can also use its single sign-on (SSO) feature to login to other applications, and access important data that they might have.
To eliminate such security risks, ADSelfService Plus provides an option to deny concurrent sessions for a user.
Steps to be followed:
- Log on to ADSelfService Plus web console with admin credentials.
- Click on the Admin tab.
- Navigate to Product Settings → Connection → General Settings.
- Check the box next to Deny Concurrent Logins. Once enabled, the user will not be able to log in from another device at the same time. Other active sessions will not be affected by this change.
Note: This checkbox will be disabled when Session Expiry Time is set to Never Expires.
Attempts to log in to the ADSelfService Plus application when there is another active session in a browser or mobile app will result in the following error message:
Reset the user's active session status:
When Deny Concurrent Login option is enabled, if a user closes a browser that has an active ADSelfService Plus session, the user will not be able to log in again until the idle session time expires. To avoid this inconvenience, you can terminate the user's session so that he can login. Below are the steps to change the session status of a user.
To change the session status:
- Navigate to Admin → Product Settings → Connection → General Settings.
- Select Click here beneath the Deny Concurrent Logins checkbox.
- A pop-up will appear asking for you to confirm that you want to close all connections. Once you click Yes, the user can now log in to their ADSelfService Plus portal again even if the previous sessions were terminated incorrectly without waiting for the idle session time to expire.
