We have got a new requirement from Legal team as they need a account which should have readony rights across all the sites.
I was wondering how It can be done but its really simple to achieve this goal.
Go to–> Central admin –> Manage Web Applications
Select the web application –>Select user policy
ADD users –> click next on ALL zones Pop up
Add user account & Assign Full read permissions
Repeat the same steps for other web application if you have.
