So not just FR update but also the OS updated too...so possible eg samba upgrade too<br>
If the RPM blatted your config like that then it may also have done something to your EAP config too - eg certificates (especially if the debug shows the clients failing at that point) . Did your windows client have correct/secure EAP settings or was it just 'user/password don't care about cert details' mode?<br>
