So, what exactly was the back-end authentication system that PAM was
using in this case? I mean, I'm not saying PAM is perfect, but it's
really just a shim to some other kind of authentication system.  I have
a hard time believing, for example, a PAM module that implemented
the traditional Unix /etc/passwd authentication would really impact
performace at all.  And if it was something like LDAP ... is it PAM
that was at fault, or LDAP?
