Virtual-link authentication and AREA 0 authentication

Folks,
I've heard statements from several people that when
OSPF area0 is configured with authentication, say,
md5, the virtual links connecting a remote area must
be also configured with the same authentication. I've
doubted it and my routers seem to be distributing
routes happily as long as the virtual-linked remote
ABR has "ar 0 auth mess". Can you help me clarify if
this is a real requirement or am I missing anything?

Thanks!
Frank
