Immediately after upgrading the replica side to AM8.6, RADIUS authentication on the replica side fails because access_id and access_key are not set in /opt/rsa/am/radius/radius_connector.ini. After the upgrade, wait about 15 minutes and this file will be updated and RADIUS authentication will succeed.
Before updating, radius_connector.ini does not contain the value of access_id and access_key.
auth_manager.radius.rest_service.access_id =
auth_manager.radius.rest_service.access_key =
Need to wait until updating each values as below.
(e.g.)
auth_manager.radius.rest_service.access_id = pbr8k26bzy09004c6m6uh458X104sse19sz02fy1qy54x8f5016z80tctu8zt468
auth_manager.radius.rest_service.access_key = s2u95191eknx7z6b1X2o64s6c1ux0kt57o4h9fez3b83cvw0v67r31m6uc79z3qx
The radius_connector.ini can be recreated after removing the file and restarting service.
