I'm having an issue where on most of our existing site collections the users specified in the "Site collection administrators" setting under "Site Settings" > "Users and Permissions" do not have the ability to see any of the 'Site Collection Administration" stuff under Site Settings in 2013.
The only way to get the Site Collection Administration stuff to show in site settings for a user is to add them as either the primary or secondary site collection administrator via PowerShell or central admin. This isn't very helpful because we will most likely have more than 2 site collection administrators in a lot of cases.
I mentioned this happens on existing site collections, and that is because if I create a new site collection, then add site collection administrators via site settings, those users do receive all correct permissions and are able to see the site collection administration section in site settings.
Therefore, this looks to be a per-site collection setting of some sort, but I have no idea what may be causing this to occur. Does anyone know how this could have happened and how to change it back to default?
