Currently eDir supports HOTP for strong authentication. A customer wants to implement TOTP using eDirectory so they could get a solution that is more user friendly (no need to resynchronize) and also more security (small window for attacks to guess the OTP code). They understand if eDir supports TOTP as well, eDir has a great differentiator in the market as other vendors would not support that.
It's very important to implement the TOTP for eDir security, this would help to reduce the possibility of attack with OTP based on time, in 60 seconds for change.
