Before you get any further, you do understand that the inifile has to be on the *master*, right? Just checking, because I've seen a lot of people trying to write functions, and only later realizing that the data they want is on the node, not the master.
When I've come up with issues like this (mainly JSON not ini, but whatever, same difference for our purposes) I put the data somewhere that Puppet can access natively (like in my ENC) and have puppet *write* files not read them.
