[quote author="m40" date="1250031075"]I have a function, lets call it validate_user, that takes two values - username and password, and matches them against a database.

Where should that function reside?

a) in a Model, because it communicates with a database;
b) in a Controller;
c) in a Library;
d) other...;[/quote]
I guess you could have validate_user() in a Authentication library and another function to query the db that would be called by the library, the latter would be in a model.

imho
