I have 3-node cluster, On first node i have installed my service in kerberos enabled mode. For load-balancer, on second node i have installed httpd 2.2.15 version, apr 1.5.2 and apr-util 1.5.4 and "./configure" , make, make install command was executed successfuly. To enabled kerberos, i have install mod_auth_kerb.so module and also added in httpd.conf, and im restarting the apache service using "./apachectl restart" it give me an error
