IPMI monitoring not available due to an error in the server log (with DebugLevel=4):

EINF: 0 ipmi_lan.c(got_rmcpp_open_session_rsp): Expected privilege 2, got 1

The error message "Expected privilege 2, got 1" means that we were requesting privilege level "user" (2) but got only "callback" (1) available. However with the same user and ipmitool the connection works:

ipmitool -I lan -H 192.168.3.133 -U foo -P bar -L user sensor
