getUserName() returns the input username and not the correct name

[Horcrux7]

The method UnixUser.getUserName() returns the same string that was pass in the method PAM.authenticate(). That the writing depends from the input. Expected is the right writing of the USER from pamlib.

A possible fix can be to replace the line:

return new UnixUser(userName,pwd);

with:

return new UnixUser(pwd.getPwName(),pwd);
