This provides a Python interface to OpenBSD's BSD Auth.
Currently it only implements auth_userokay(3) since this is most
suitable for authenticating to OpenBSD from Python.

Your application must have root privileges in order to use this module.

Usage:
>>> from bsdauth.bsdauth import UserOkay
>>> uo=UserOkay('user','goodpassword')
>>> uo.login()
True
>>> pw='badpassword'
>>> uo = UserOkay('user','badpassword')
>>> uo.login()
False
