    will be ['.', profile.security_dir]
    
    Parameters
    ----------
    
    filename : str
        The file to be found. If it is passed as an absolute path, it will
        simply be returned.
    profile : str [default: 'default']
        The name of the profile to search.  Leaving this unspecified
        The file to be found. If it is passed as an absolute path, fname will

    Returns

    Raises :exc:`IOError` if file not found or returns absolute path to file.
