[FLOW3-general] Log into system

[Dawid Pacholczyk]

Hi List,
  I`m trying to understand one thing. How should I create login action 
for my system ? If I have my own User model (where this model holds the 
password) should I copy the code from Blog example ?

I see there that LoginContoller injects AuthenticationInterface. But for 
me interface should be implemented and the object should create methods 
declared in the interface. Can I do that ? Or should I do it in other way ?

Best regards,
Dawid Pacholczyk
