The usage of an Azure AD Application has advantages as well disadvantages. One of the disadvantage is that Microsoft limits the amount of concurrent sessions for an Azure AD App.

The current limit is 5 concurrent sessions per app. (March 2018)

If you see an error messages like "You have been disconnected because your most recent sign in exceed the server limit" in the log.txt of the Bot or in the appliance log, then you ran into limitation with your current OE configuration.

There are several reasons for that:

  • too many Simulation Bots running at the same time
  • Simulation Bot and Appliance are sharing the same Azure AD App

 

Solution

Create and use a dedicated App for the Bot as well for the Appliance instead of sharing one.
Customers can create as many Azure AD Apps as they like (no limitations)
