You need to find out how they send the auth to FreeRADIUS. Likely PAP,
but might not be. PAP or MSCHAPv2 should be workable. Anything else,

I guess sssd gets its information via LDAP? You're may as well just
configure FreeRADIUS to use LDAP directly, rather than to try and get
it to talk to the OS and do it that way.

But if the switches don't do PAP, then you're probably stuck anyway. AD
won't give you any sort of password to check.
