I have installed openfire server 3.6.2 and I am using spark 2.5.8.
I have customized spark client as per my need . I want only the customized spark to be able to connect to my server.
But now user can download any version of spark and able to connect.
How do I restrict from OpenFire so that it will accept connection only from the spark client that I have modified.
Please suggest how to proceed.
