The following INFO-level log entry is seen in the VIP RADIUS validation server logs
INFO "2019-07-10 10:41:40.877 GMT-0600" 0.0.0.0 SRAS:1814 0 0 "text=After Services Authenticate call for user [<User-Name>]. StatusCode: 24585, StatusMessage: Authentication Failed." Thread-7552 VSAuthOTPStandardControllerImpl.cpp
Radius Validation Server running ULO mode with Access-Challenge enabled
This end-user is not entering their VIP security code along with their password during 2FA login, and is entering the code when being challenged, or on the initial login push enabled credential and is accepting the push as it is received on the mobile phone.
This is a false-positive error seen in the logs when the user's LDAP password is alpha-numeric and VIP attempts to validate the digits as the OTP. (please see: Delegation and authentication workflow in VIP Enterprise Gateway version 9.8 and later). This is normal behavior with zero negative impact to the user's VIP account:
