This problem described about the multiple user login sessions in Microsoft Dynamics NAV 2013.
The problems happens at our two Dynamics NAV 2013 implementation sites. The Dynamics NAV 2013 creating Multiple Active Sessions for a single user log in. This problem happens regularly to all users irrespective user rights and user type. In which when a particular user logs in, at the Dynamics NAV 2013 server side it creates multiple active sessions automatically. At one point of time, all these active sessions added and exceeds the number of user limits in the License. Though there is a room for the more concurrent user logins allowed as per the License, system prevents and other users to log in.
We have configured with minimum session logout time.
The active multiple sessions are cleared when the NAV server is restarted.
If any of you encounter this problem at Dynamics NAV 2013 implementation sites, please provide your possible step to prevent this.
