I would like to get an idea that how we can enable MFA for linux based application basically which are hosted in linux machine and we access it by logging in to linux machine. How can we enable MFA for those apps or how can we enable mfa for linux/unix platform login in general. Have some conceptual idea that we can enable linux/unix machine as radius client and configure OpenAM as radius server. Basically i am more interested to know what configurations we need to do at AM level other than radius client creation to incorporate mfa to that radius client (unix/linux). Any help would be highly appreciated.
