Not an OSPF expert by any means!! but have dealt with authentication before.

1.    All routers with I/F's in the same area must be configured with the same method, key and pwd.

2.    Under your  ' ROUTER OSPF ## '   (of each router ) include:
                            area #  authentication message-digest'

Hope this helps.
