I’ve removed the rules. This has not changed the situation, though.
I have a folder, ‘Windows’. I’ve modified the properties of this folder by selecting the permission tick box and moving both ‘Everything’ and my own ‘noc-users’ contact groups into the ‘Selected’ Column. I ticked each of the four related boxes below the table.
I’ve confirmed that my ‘normal monitoring user’ appears inside of the noc-users contact group. My expectation is that all hosts in this folder will be visible in the dashboard and in Monitor → All Hosts.
When the user logs in with this configuration however, he can see the folders and hosts within Setup → Hosts → Main but Monitor → All hosts and the default (main) dashboard are both empty.
Within Setup → Hosts → Main, I see both ‘Everything’ and ‘noc-users’ contact group icons displayed on the desired folder. The host and user association with the contact group are both there and aligned.
