kerberos pids not written and not checked by init script or handled by agent on CentOS

[Stephen Ingram]

In zivios 0.6.3 on CentOS 5.4, kerberos pids are not always written on startup. Init script should ensure that the pids are written to files in /opt/zivios/heimdal/var/run directory. "The agent module throws the error because it is expecting an int during comparison and finds null."

From /var/log/ziviosagent.log:
