This means that you are not running with an APF authorized library. Make sure that if you are concatenating libraries that all libraries in the concatenation are APF authorized. You should check your logon proc to see if there is a STEPLIB DD that references any dataset(s) that are not APF authorized which would strip the authorization off of the ones that are APF authorized.
