1.2.13 Clients Might Have to Re-Register After an Upgrade

After a Spacewalk server is upgraded, Spacewalk clients might have to re-register with the Spacewalk server. The web interface shows these clients as registered, but when you run the rhncfg-client command on the client, errors such as Authentication failed: Invalid digital server certificate are displayed.

If this problem occurs, use either the rhn_register command or the rhnreg_ks --force command to re-register the client.
