Oi Jurandy,

Some Posix functionality is available in the Mono.Posix assembly
(overview here http://www.nullenvoid.com/mono/wiki/index.php/MonoPosix).

It looks like there is not much of PAM integration classes there, so
you my need to write some code yourself to P/Invoke in the correct
libraries (because probably your code won't have direct access to the
passwords file in /etc, and may need to be more useful than this
Python example that doesn't work well with shadow passwords).

Você conhece o MonoBrasil (http://monobrasil.softwarelivre.org/twiki/bin/view)?

Sorry for not being able to really help you with this...
