include accounts in LDAP admin role, add demon

- add demon (he had these permissions without needing
  sudo, because he had root on formey in the past)

- the users who get sudo need to be included as well, duh

- add wikidev group, this is always needed in all admin classes

RT #6134 (replace formey LDAP operations)
