Hi, all I follow the offical install instructions and place auth.pp into /etc/ puppet/modules/ssh/manifests/. offical site: http://projects.puppetlabs.com/projects/puppet/wiki/Module_Ssh_Auth_Patterns But I got the following error when running puppet: err: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not match ''class'' at /etc/puppet/modules/ssh/manifests/ auth.pp:10 on node xxxx I guess I may omit some necessary install steps, but I don''t know what they are.
