Continuous Re-authentications

ericstover1 — Mon, 11 Mar 2019 05:18:01 GMT

We are in the process of migrating from ACS 4.x to ACS 5.5. At our smaller branch offices we have Sonicwall TZ205/215 that act as a wireless AP. The SSID uses RADIUS to authenticate users. I've noticed that wireless clients at these sites are endlessly authenticating. One example is that a user authenticated 21 times in 10 minutes. The authentication method listed was Lookup for all 21 occurrences. Is this normal behavior? I would like to think there is a client configuration issue or a timeout issue on the Sonicwall.
