On the Home Agent, syslog entries similar to the one below indicate authentication
errors for non-AAA Mobile Nodes:

Mar 20 17:05:55 ERROR: HA: authentication failed from MN

Solution Compare the security configuration for the Mobile Node on the Home Agent
with the configuration on the Mobile Node. Check that the security algorithm and
security keys match.
