When the FIX adapter configured as an order server or market data server, it allows the Apama application to authenticate client sessions. To enable client authentication, set the ValidateLogonRequests property in <transport> section of the adapter’s configuration file to true and create an application to validate client sessions by listening for com.apama.fix.Logon request(s) and replying with com.apama.fix.LogonAuthenticationStatus events.

When the ValidateLogonRequests property is enabled for a server transport, for each logon request from a client it will wait for up to the number of milliseconds specified by the LogonValidationTimeout property to receive a LogonAuthenticationStatus event from the Apama application.
