In the SUSE Manager Server, the jabberd DB should be recreated:
# spacewalk-service stop
# rm -Rf /var/lib/jabberd/db/*
# spacewalk-service start
The same applies for the proxies:
# spacewalk-proxy stop
# rm -Rf /var/lib/jabberd/db/*
# spacewalk-proxy start
In the clients, the osad-auth.conf file should be deleted:
# rcosad stop
# rm -f /etc/sysconfig/rhn/osad-auth.conf
# rcosad start
Obviously this step can be automated through SUSE Manager, specially in the case of having several clients. The task will be eventually run after a maximum of 4 hours. It can also be forced by running the following in the client:
# rhn_check
However, this requires logging into every client.
