Moodle plugins directory: CSV Enrolls & Groups plugin

@csaba... the safest way to do this without waiting for a version update, is to comment out three specific lines in the plugin's lib.php file, lines beginning at 217 which look like the code below. Commenting out the case statement for 'idnumber' and the next two lines will make the regular expression used for idnumbers the same as the one used for usernames (default), which allows for a field beginning with an alpha, or numeric, and followed by more alpha, numeric, underscores, and dashes.

// Choose the regex pattern based on the $ident_field
switch($ident_field)
{
case 'email':
$regex_pattern = '/^"?\s*([a-z0-9][\w.%-]*@[a-z0-9][a-z0-9.-]{0,61}[a-z0-9]\.[a-z]{2,6})\s*"?(?:\s*[;,\t]\s*"?\s*([a-z0-9][\w\' .,&-\[\]\{\}\(\)]*))?\s*"?$/Ui';
break;
//case 'idnumber':
// $regex_pattern = '/^"?\s*(\d{1,32})\s*"?(?:\s*[;,\t]\s*"?\s*([a-z0-9][\w\' .,&-\[\]\{\}\(\)]*))?\s*"?$/Ui';
// break;
default:
$regex_pattern = '/^"?\s*([a-z0-9][\w@.-]*)\s*"?(?:\s*[;,\t]\s*"?\s*([a-z0-9][\w\' .,&-\[\]\{\}\(\)]*))?\s*"?$/Ui';
break;
}

I apologize for the difficulty. As I look at this, I should have made the idnumber field validation more flexible, rather than specific to our environment. I will make a change to the plugin at some point in the near future.
