Role of Secure Channel Re-authentication Enabled

On opc client connection :
What is the purpose of this parameters Secure Channel Re-authentication Enabled ?
Not described in doc.
OPC connection settings has changed in 7.8.2 with discovery and new parameter ?

This is basically just a workaround for a Kepware bug. Ideally, it should be left at its default setting, but if you’re having trouble with a Kepware connection not reconnecting this can help.
