Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit).

Description of problem:
Restrict edit_params & create_params to set host parameters only on hosts that user owns

Version-Release number of selected component (if applicable):
6.2.12

How reproducible:
everytime

Steps to Reproduce:
1. Define that filter 
Host 	build_hosts, create_hosts 		lifecycle_environment = "SomeEnv" 	
Host 	destroy_hosts, edit_hosts, view_hosts 		owner = <someuser> 	
Host 	power_hosts 		owner = <someuser> 	
Parameter 	edit_params, create_params 		none 	
Domain 	view_domains 		name = <somedomain>

2.Create new parameters on a hostname that is NOT owned by someuser
https://satellite/api/hosts/hostname/parameters
with json for example.
{
  "name": "groups",
  "value": "<group1>"
}

Actual results:
POST is succesful even that hostname is not belonging to someuser and not visible on All hosts page by that user

Expected results:
User is restricted to change/add parameters only on his own hosts
