Created redmine issue http://projects.theforeman.org/issues/19934 from this bug

This is really an RFE, the field 'Order' is only meant to contain the types of matchers, not the values of the matchers themselves. 

fqdn
hostgroup
os
domain

Instead I believe you want to input hostgroup labels directly and have Satellite automatically understand you want to match hostgroups params in a certain order.

We can trivially remove the limit but it won't help with the goal you have, as the field isn't meant for that, hence why I'm changing it to RFE (it makes sense though)

Hey Daniel, no that is not the case. Our use case is *simply* that this field is not large enough to contain all the types we need to add.

Our environment is global. As the matchers are simplistic (key = value) we simply have a fact that returns a key for each AD group a server is a member of and set the value to true. 

# dzdo facter -p | grep gsd
gsd-all-00-ob_n_dhporacledvsz => true
gsd-all-00-ob_n_dhporacledvsz30 => true

This has certain advantages over checking if the value is in an array in that we can be deterministic with priority (i.e if a server is in multiple AD groups)

Our matchers then are:

if gsd-all-00-ob_n_dhporacledvsz = true then <value>
if gsd-all-00-ob_n_dhporacledvsz30 = true then <value>

Hope this clarifies. 

In our lab we have updated the length of the path column to 1024 chars. We need a support commitment before we can do the same to production though.

Moving this bug to POST for triage into Satellite 6 since the upstream issue http://projects.theforeman.org/issues/19934 has been resolved.
