Error logging in when StaffPreviousPasswordCount Customization Key is less than one
When you set the StaffPreviousPassword to 0, Aeon should default to checking a minimum of 4 unique passwords before an old password can be reused. Instead, a bug is causing the system to read the 0 as a null value, which in turn made it to unable to recognize any passwords. Until the bug is fixed, do not set the default value to 0.
