This is only happening on IE, but when we use Chrome we do not have any issues using the account password. The problem is that we have admins that use only IE. We are using IE11 at our company. I searched the forums and did not find anything on this.
Passwords are case sensitive and can contain numbers and characters up to 20 characters.
I would assume the situation you are addressing is just comparing against the 1st 20 bytes of the password, where a value check on the other is stopping you at 20 bytes.
