I would like to know if it is possible to authenticate linux users through Okta, looking at the help center I found some answers but it is not clear whether it is possible or not. I checked that Windows have the Microsoft RDP (MFA) application, is it possible to do without MFA? Only login ?
RE: MFA For RDP - you can create a sign on policy in the application to bypass MFA For a specific user. that user needs to be assigned to the app, but you can choose to exclude them from the app level sign on policy
Note: currently it only support PAP not EAP so you need to be mindful of that and ensure the connection from the client to the radius agent is secured or use a RADIUS gatway like FreeRadius to proxy it.
There is also another thread detailing it here: https://support.okta.com/help/answers?id=9062A000000QuncQAC&feedtype=SINGLE_QUESTION_DETAIL&dc=xProvisioning&criteria=OPENQUESTIONS&
