Checking that the username is valid is easy enough -- create a
UnixUserInfo instance.  An ArgumentException is thrown if the username
is invalid:


Alas, I don't know how to check the password, as the
UnixUserInfo.Password property doesn't contain the password hash (at
least on systems with a "shadow passwd file," which is most/all current
Unix systems).
