[TYPO3-typo3org] TCA['feuser'] sort

[Lbarrien]

Hello, i need to sort the fields of the fe_user's backend form.

I don't know where paste the
$TCA['fe_users']['feInterface']['fe_admin_fieldList']=  field1,field2;

I read the documentation and i tried put in almost conf.php - but nothing.
Any idea?

See ya!
