As a LDAP proxy server, it's connected to your base LDAP backend (ex. ActiveDirectory, Novell, 389...) and it transparently provides OTP login mechanisms for the existing LDAP users. Because it's a tranparent proxy, it make it possible to impement multi-factor authentication as well as complex WebADM access policies for legacy applications which do not support other authentication mechanisms than LDAP.
