Small memory leak

[brockrob]

I fixed this in mine, but I'm beginning to suspect our forks are diverging.

There's a small leak in dllmain.cpp. pfAccount in the PasswordFilter function needs deleting when you're done with it. It's a struct of pointers, so if a domain controller is up long enough for those to pile up and kill something you probably have bigger issues, but still, a leak is a leak. :)
