Re: [Quickfix-developers] Logon passwords

[Vincent P. <vpr...@ph...>]

I didn't get a response today, and I do need to get this figured out,  
so I will clarify exactly what I need to do:

I'm writing an ecn engine that will accept logins from multiple user  
clients, so I need to handle both the sending and receiving of the  
Logon message.  I'm still a little confused because I read on the  
forum that I could use the fromAdmin handler to verify the password.   
However, when I wrote code to do that, the fromAdmin handler never  
fired when the server app received the Logon message.

Unfortunately, searching for "Logon message" and other variants turn  
up over 1,000 matches to scour through, so it's difficult to find the  
correct answer if this thread has already been touched upon. :)
