[indra < >]

Hi,

    I am using open source chef server,in which pem files are not 
created in /etc/chef-server only two files are there 
1)chef-server-running.json2)chef-server-secrets.json

    I ve extract a pkg using
           1)dpkg -i pkg name  then
            2)use sudo chef-server-ctl reconfigure
but its not creating pem files why?

Thanks,
 Indra
