For SSO is no longer work that has been operating in the version of 6.1.x, I want to run in legacy mode.
However, if it set to appServerPorts = 0, it will fail to start SplunkWeb service.
===============================
....
Starting splunk server daemon (splunkd) ...
Splunkd: Starting (pid 6668)
Done
It's solved with reinstall.
Thanks,
