Kerberos (PennKey) Authentication for OS X 10.8 "Mountain Lion", 10.9 "Mavericks" and 10.10 "Yosemite"

Allowing users to log in with their PennKey is the best way to provision access to public computing resources. Everyone at Penn has a PennKey and password, that is all they need.

Prerequisites: Mac OS X 10.8.5/10.9.5/10.10.4, PennNet IP address, Kerb access to the Penn Directory.
