Hi,
I just installed SP 2013 in least privileges scenario and wanted to create new web application using Central Administration's app pool user. Unfortunately option in ribbon is grayed out. After I added CA's app pool user to local admins I am able to
create web application. I recall that this permissions was not required in SP 2010. Additionally I cannot find any info in installation guide that this user should have such a permission.
Thanks in advance
