I just use either javascript or php to see how long the password is and send the user an error message if it is not long enough.

could you be more specific on how to see how long the password is and send the user an error message if it is not long enough.

Is Your AD Toolbox Looking More Like a Toybox?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

Can someone give me php code that allows me to check the password to make sure it is a minimum of 6 characters and gives an error if it is not? I don't know code...Thanks!

say the password is $_POST['password']

$passwordlength = strlen($_POST['password']);

if ($passwordlength < 6)
{
    I need to know the code for the whole form to know what to put here, I am thinking maybe javascript is a better way to handle this, so you wouldn't use this at all. But I need to see the code
