Bill,
I think you need 'area 0 authentication message-digest' for the virtual link
to be doing authentication, since the virtual link is like a link into area
0.

Sure.
Here is my area 0 router:
The VL is coming in over the e0 interface, but because i am only trying to
authenticate the VL router I do not put any authentication information
there, it
is under the ospf process.
!
interface Ethernet0
ip address 10.0.1.1 255.255.255.0
ip ospf priority 100
no keepalive
!
interface Serial0
ip address 130.10.1.1 255.255.255.0
encapsulation frame-relay
ip ospf message-digest-key 1 md5 cisco
ip ospf priority 100
!
router ospf 64733
network 10.0.1.0 0.0.0.255 area 10
network 130.10.1.0 0.0.0.255 area 0
network 1.1.1.0 0.0.0.255 area 1

neighbor 130.10.1.5 priority 2
area 0 authentication message-digest
area 10 virtual-link 5.5.5.5 message-digest-key 1 md5 cisco
Here is my remote router:

full-duplex
service-policy output QoS-Policy
