RIP MD5 follies

I know I'm not the only one that despises MD5 authentication. Seems like
there aren't too many other things in IOS-land that are as unpredictable
when it comes to doing what it is supposed to be doing.

I have SW2 and BB2 from an IE lab that are supposed to exchange RIP routes
using MD5 authentication. I've reloaded both devices, verified the configs
(yes, I cheated and looked at BB2 ;-) on both but the debugs on both sides
continuously complain about the auth. I even checked the solution guide and
my config is identical except the name of the key chain name.

key chain RIP
 key 1
   key-string CISCO

interface Vlan82
 ip address 192.10.1.8 255.255.255.0
 ip rip authentication mode md5
 ip rip authentication key-chain RIP

Anybody out there have a good method for clearing this type of mess up?
