Good day- we have same issue too - tried an APSP1 for code 17.9.2 yesterday it still fails ...have not downgraded or upgraded - prefer to upgrade if it is fixed in a later release.
Did you ever get this to work ? What if anything fixed it ? Seeing similar issue with painfully slow auths or failed auths on Windows 10 clients on code version 8.10.130.0. Sometimes they will connect other times not. Random.
Has anyone used Cisco ACS TACACS with the Catalyst 9800 WLC ? Having issues with device not recognizing all the menu options even with priv 15 access set up , all we are seeing is the Dashboard and Monitor. Using code 17.3.3 AireOS WLCs are working...
