I use endian 2.2 RC1 for proxy server , I create user for access internet.

All user can change you password via https://endian:10443/cgi-bin/chpasswd.cgi

but when user fill all info and click bottom change password it show error this below

E R R O R     E R R O R: Username does not exist

What problem and how to solved this ?

many thank
