Please have a look at this discussion and see if it helps solving your problem as well:

https://supportforums.cisco.com/discussion/12428001/asr900-ospf-4-novalidkey-no-valid-authentication-send-key-available-interface

Otherwise a 'debug ip ospf adj' should provide useful information. If you have many non-passive OSPF interfaces, you should limit the output with 'debug condition <ospf-interface>' first.
