How to prevent Vim from automatically indenting new lines?

Question

I use vim to edit a lot of latex files using vim 7.4. Some trick of the syntax indenting annoys me and interferes with my intentions. Particularly, the automatic indentation during the addition of a line. I tried to remove this by

:set noautoindent

but it produces no effect. Which of the many options is working against my desires?

Answer 1

After examining similar questions, I've found the solution is to :set nosmartindent.

Answer 2

I had this just recently and my solution was different. My vim setup was:

:set
--- Options ---
  background=dark     history=200         langnoremap       nomodeline            ruler               scrolloff=5         ttimeout            ttyfast             wildmenu
  display=truncate    incsearch         nolangremap           nrformats=bin,hex   scroll=37           showcmd             ttimeoutlen=100     ttymouse=sgr
  backspace=indent,eol,start

if you pay attention, backspace has indent on it...

setting it differently (just removing the indent)

:set backspace=eol,start

solved the issue
