what are the admin equivalent roles in SharePoint server 2013? E.g. what would an administrator of a SharePoint environment typically be granted to allow them to do their duties? I.e. sysadmin equivalent in MSSQL? enterprise admin in exchange etc.
Also out of interest (very novice query), if a SharePoint admin needed to add a user to a SharePoint environment so they could view content on a site, or amend permissions to documents on a site, what management tool within SharePoint would they use?
