Maybe someone here knows a solution. The ONLY thing keeping me on windows is that my employer uses F5/Big IP edge clients. I cannot find a Linux client that can also handle Web SSO. Does anyone have any Linux experience with this?
I did fight with that a few years ago. Memory is that you can get through some steps running Windows in a VM to get thru MFA checks, and then close it later.
I'm no expert here, but my employer uses no less that three different SSO services (don't ask).., and all of them work under Linux.
Web-based really ought to work. Maybe your admins are being weird, and checking the user agent? Try using a plug-in to change your user-agent to Windows
