VIP Authentication fails when Authentication Sequence for VIP is set to Security Code + Ldap Password.
This is by design.
Regardless of the selection of sequence (for LDAP Password and OTP) we make in VIP EG Configuration Console, end users would have to login in this format:
UserName: - Username
Password: - LDAP Password + OTP
Selection of sequence only changes the order of Validation of the OTP and LDAP Password in cloud. For example, if you select the sequence as LDAP+OTP, the validation will first happen for LDAP Password and after that for OTP. And if you select the sequence as OTP+LDAP, then the validation will happen first for OTP and then for LDAP Password.
But in either case, end users would have to enter username and password as follows: username and LDAPPassword+OTP.
