FluorineFx error in log file

I found out there is the following error in log file
ERROR FluorineFx.Messaging.MessageServer [(null)] <(null)> - Failed to locate the requested type com.TheSilentGroup.Fluorine.Messaging.Security.GenericLoginCommand
What does this error mean?

This problem is caused by an incorrect setting in your WEB-INF/flex/services.config, which most probably looks like this:

   <login-command class="com.TheSilentGroup.Fluorine.Messaging.Security.GenericLoginCommand" server="asp.net"/>

This setting comes from an old configuration template and as it is not needed for a web based access it can be safely removed.
