How can I’ll be SharePoint farm Administrator? By Adding Farm Admin group from SharePoint Central Admin site as shown the below I’ll become Farm Administrator?
But as we have expected by completing all the steps, these will not grant Farm Admin privileges on the server. These steps will add user to farm admin group in SharePoint and WSS_ADMIN_WPG group in SharePoint farm. By updating user to this farm admin, users get access to web site and access to SharePoint resources as logs and web services.
If user not added in SharePoint local Admin group, user is not fully-fledged SharePoint farm administrator. When user runs SharePoint management he will see "The local farm is not accessible. Cmdlets with feature dependency ID is not registered."
To execute PowerShell commands, users need SharePoint_Shell_Access in SQL server SharePoint configuration database and other databases where we need to manage the data.
Therefore, to make a user as SharePoint farm admin, he need to have following permissions,
· Local Administrator security group for each server in the farm
· Farm Administration SharePoint Group
· SQL Server SharePoint_Shell_Access database role for the SharePoint configuration database and all content databases.
