Cannot map <Tab> to auto completion

[Ansman]

No matter what I do I cannot bind <Tab> to autocompletion in insert mode.

I've tried removing my vimrc and just having set nocompatible and it still doesn't work.
Running :verbose set cp? wc? shows
nocompatible
        Last set from ~/.vimrc
  wildchar=<Tab>
        Last set from ~/.vimrc

What am I missing?

P.S. <ctrl>+<n> works just fine.

Strange nobody replied to this.

'wildchar' only applies to commandline mode, not insert mode.

I make <Tab> work the way I want it in insert mode, and enabled by
default only for PHP files, with this in my .vimrc:

function! TabCompletion()
    inoremap <buffer> <expr> <Tab>
       \ col('.')==1\|\|match(getline('.')[col('.')-2],'\s')!=-1?
       \ "\<Tab>":"\<C-N>"
endfunction
function! TabCompletionOff()
    iunmap <buffer> <Tab>
endfunction
command! TabCompletion call TabCompletion()
command! TabCompletionOff call TabCompletionOff()
augroup TabCompletion
    au FileType php TabCompletion
augroup END

You may find this helpful.

Smiles,

Ben.
