If username is not admin or it is not present in administrator group will that user is admin ? If yes then how to indentify the the user is admin or not?

As far as I know: A recently created user will be not assigned automaticly to a group or role. When an instance is installed, there is a process which creates groups and assign rights, so you are able to get started.

@akshaybhujbale check the ACL for the particular user and what level of R/W access it have via /useradmin.

Hi @Mayank_Gandhi 

But which are the permissions which make normal user as admin?

@akshaybhujbale you don't become admin as in name, but ACL gives you permission to do similar tasks. So you should check ACL to see what all access this user has if not in admin grounp. Admin has R/W access to every path
