Today I am checking out Acegi Security for our app. I'm slapping it against the application now, early on, rather than trying to shoehorn it in later, after everything works in an insecure fashion.
I would like to know how the hell it's supposed to be pronounced.
It certainly looks cool. Pretty pluggable. Should fit reasonably well within our current application design; I'm just going to write a UserDetailsService implementation that uses our existing Hibernate configuration.
More as I actually do it.
