Restricting User IDs to Single Sessions
To restrict a user ID from signing on multiple times using different browsers on the same machine or the same browser on different machines, modify the portal.properties file. The last browser session with the user ID to login will have access to the portal. Other browser sessions with same user ID will be logged out.
The portal.properties file is located here:
Linux:
/opt/aptare/portalconf/portal.properties
Windows:
C:\opt\aptare\portalconf\portal.properties
1. Update the following section:
portal.security.allowUserToLoginMultipleTimes=false
2. Restart the Tomcat Portal services after making your modification.
