Provisioning on vsphere 6 / Content library?

Good day,
We recently began testing provisioning on Vsphere 6 with foreman.
Has anyone been able to get foreman to correctly find a template that is
stored within the content library?

I attempted to simply call
ContentLib\ms_2012r2_base
ContentLib being the content library name followed by the template name.

It would be nice, otherwise it means copying a template to each vcenter.

Thank you for any help.
