AdminCP didn't recognize changed password

[Snowhog]

Thank you for replying Lynne.

No, I didn't change the length of the password field.

So, while the password field in the UserCP (Settings > Edit Email & Password), which is 'large' and will accept more than a 50 character password, it must be truncating anything over 50 characters.

When logging in to the Forum, the password field is 'short', but pasted content gets accepted. So apparently there, it also must be truncating the input.

When logging in to the AdminCP, the password filed is 'large' and will accept way more than 50 characters. But there, it must not be truncating anything over 50 characters, thus the invalid password notification.

Have I got this correct?
