Module to control commenting permissions by role and by node type.

Code

function comment_perm_access($node) {
  global $user;

    $node = node_load($node);
  }

  // get node types managed by comment_perm
  $types = variable_get('comment_perm_node_types', array());
  if (isset($types[$node->type])) {

    // allow comment administrators to post wherever they want
    if (user_access('administer comments')) {
      return TRUE;
    }

    // get assigned permissions for this user's role
    $access_moderated = user_access($node->type . ': comment on any ' . $node->type . ' content');
    $access_all = user_access($node->type . ': comment without approval on any ' . $node->type . ' content');
    $access_own = user_access($node->type . ': comment without approval on own ' . $node->type . ' content');

    // does the user have permission to post comment on nodes of this type?
    if ($access_moderated || $access_all) {

    // comment_perm controlled node types default to no permissions

  // non-comment_perm controlled node types default to whatever permission Drupal gives them.
