Hi I am very new to puppet and wants to implement something like this in my puppet template (erb file) the logic i am trying to do is : sssd_count=`rpm -qa | grep ''sssd'' | wc -l` <% if sssd_count =2 -%> session optional sss.so <% else %> session optional pam_ldap.so <% end -%> but the backtick does not work.. or i am unable to store the expected value in to sssd_count is there any other way to perform this task ?? I will be really grateful if i can get some help .. Thanks -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

If you are managing sssd* package(s) via puppet, you can try this:
module.pp -
if defined(Package[''sssd'']) and
defined(Package[''sssdxx''])
{
$session_variable = "sss.so"
}
else
{
$session_variable = "pam_ldap.so"
}
template.erb -
session optional <%= session_variable -%>
