l_struct = cast(l_res, POINTER( Struct_Password ) )
POINTER wants a ctypes type as an argument. Struct_Password() is a
Structure instance.
A better way to do it is define the return type for getspnam:
g_lib.getspnam.restype = POINTER( Struct_Password )
Now the function returns a structure pointer so the cast is unnecessary.
