Our VPN client limits the number of characters that can be entered in the password field so it is not possible to append the OTP to normal password. Is there any solution?
YubiRADIUS 3.5.1 (and later versions) support the option to allow users to append the OTP to the username instead of their password. Further details can be found under section “Setting up the Global configuration parameters” of the YubiRADIUS Configuration Guide, which is available from the YubiRADIUS Download Page.
