Due to the recent amount of hacks it would be nice if the user was forced to enter a 'stronger' secret if they enter one at all. I've created a patch that enforces a user to use at least six characters, two alpahabet characters are required, as well as two numerals.
Testing of these patches proceeded as follows:
1) Tested both ie7 and ff3
2) Tested both extension and device user mode
3) Tested to make sure that if you go into an existing extension and edit something besides the secret it will let you continute. Some times you need to make a quick change and you don't have time to pick a newer, tougher secret, as well as reconfigure the phone. Ethan's new module takes care of giving you a list of extensions that you need to update anyways.
Thoughts:
I bumped into ticket #3266 and I believe that this should also resolve that ticket.
