Hi Val, the procedure you reference is a CP Internal only SK.
I was able to solve a similar situation with the following commands:
service ipmi start (launches the tools)
ipmitool lan print 8 (shows the network config of the lom card (makes sure you are pointing at the correct channel))
ipmitool user list 8 (shows a list of the defined users (admin is generally 2))
ipmitool user set password 2 Password1 (sets the admin password, should be at least 8 characters, upper/lower and a number helps)
service ipmi stop (stops the tools)
NOTE: the newer LOM cards have some different parameters as they are idrac based
