I tried this while back, and it did not work for me neither.
Only thing I could do was to create virtual link and/or Tunnel interface.

I am not sure either of these solutions are acceptable.

Subject: Per Interface Authen in OSPF

Hi,

I tried to get per link authen to work but didn't succeed. ( Until I read
Brian Dennis's post I didn't know per link authen was even possible)

I looked at Cisco OSPF's support page but couldn't find any sample config's
so I tried the following approach: Don't use the "area x authen" under
router ospf, instead do the following

R1 s0 ---- s0 R2

R1 config

int s0

ip addr x.x.x.1 m.m.m.m
ip os authen
ip os authentication-key 0 ccie

router ospf 1
net x.x.x.0 0.0.0.255 area 0

R2 config

int s0

ip addr x.x.x.2 m.m.m.m
ip os authen
ip os authentication-key 0 ccie

router ospf 1
net x.x.x.0 0.0.0.255 area 0

This didn't work even though both routers are running IOS 12.1.

Anybody see what's wrong with this config? Thanks, Raj
