Resolution

1)Verify the correct password using the below command

# psql -U susemanager -h 127.0.0.1 susemanager

The correct password results in successfull database login. The wrong password results in the below error:

"psql FATAL password authentication failed for user susemanager"

2)Once the correct password is known, modify the password in the configuration file /etc/rhn/rhn.conf.

3)Restart the spacewalk service.

#spacewalk-service restart

Cause

The password in the configuration files /etc/rhn/rhn.conf and /etc/salt/master.d/susemanager_engine.conf was incorrect.
