How to prevent concurrent logins for a user in ADSelfService Plus

Concurrent logins give users extra flexibility by allowing them to log on to the network from multiple endpoints simultaneously. However, compromised credentials could be used by illegitimate personnel to log in at the same time as the legitimate user to authenticate to the network. This could also lead to multiple security issues within the organization like misuse of the user's personal information or resources they have access to. This concurrent login vulnerability can also result in the user being wrongly held accountable for the malicious actions of another user.

In ADSelfService Plus, when a user is logged in from multiple clients simultaneously, it increases the chances of valid but compromised credentials being misused to perform illegitimate password self-service operations. To make matters worse, the unauthorized users can also use the single sign-on (SSO) feature to login to other applications, and access or modify sensitive data.

To eliminate such security risks, ADSelfService Plus provides an option to prevent concurrent logins for users.

Steps to be followed to restrict simultaneous logins:

  • Log on to the ADSelfService Plus web console with admin credentials.
  • Click on the Admin tab.
  • Navigate to Product SettingsConnectionGeneral 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.

Once done, concurrent logins into Active Directory will be prevented for all the users in the respective domain or OU.


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.



Mobile app:


Reset the user's active session status:

When the 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 until the idle session time expires. To avoid this inconvenience, the admin can terminate the user's session so that they can log in again.

To change the session status:

  1. Navigate to AdminProduct SettingsConnectionGeneral Settings.
  2. Select the Click here option beneath the Deny Concurrent Logins checkbox.


  3. 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 ADSelfServicePlus portal again, even if the previous sessions were terminated incorrectly and without waiting for the idle session time to expire.
