RBAC (Role Based Access Control)

General scheme.

• Create role.
• Create user and assign a role.
• Create an object and assign a privilege tag.
• Assign the privilege tag to a role.

Based on this the following script was created to pull all the role, user, object and privilege data out of a customer system.

Why poller node graphs are not displayed

This usually is due to we have not set omkd_url_base OR (opcharts_url_base and opcharts_hostname) in the poller. This is how it works: 

• opCharts generates a registry file on application startup (When needed). For this registry, it uses one of this urls. 
• When this registry is generated, it creates a file for each application in var/registry/opcore/registry
• When opHA synchronises data from the poller, it also updates the registry information for each application. 
• opCharts in the Primary will use the opCharts registry from the poller to generate the remote url for the graphs. 

If the keys opcharts_url_base and opcharts_hostname are not defined, it was also causing issues (Lab test)
