Hi Seth. At first look that seems like it would work. I got a little
confused with you creating a variable called user but instantiating a CFC
called "login", but that would be easy enough to clarify.
When I've done this sort of thing, I've used the <cflogin> tag, which means
your LoginManager can check against getAuthUser() to determine if the
current user is logged in. That lets you eliminate some of that checking
from the UserLogin object.
As an aside, when you are reading from shared scope variables like the
session scope you don't need an exclusive lock. Exclusive locks are for
writing to the variable, readonly locks are for reading. In fact, as long as
you are diligent about exclusively locking all of your writes to shared
scopes, you don't even need to lock the reads.
Hope that helps,
Brian
