Group,
Recently, my AD servers were patched by another support group and this
caused a (small but noticeable) service outage for our WPA radius
services (Radius 2.1.9)
I can think of two things to investigate:
* Recent Samba can do winbind credential caching IIRC - I haven't
experimented with this so I'm not sure if it will work for this application.
* Enable Fast Session Resumption:

... We dropped the hits on our DCs by > 40% by doing this. N.B Resumed
sessions will not touch your inner-tunnel config, so you have to make sure
that you pay attention when (re-)assigning VLANs / other returned
attributes based on username.
