When testing IPMI credentials, the error message shows that we do not have the ADMINISTRATOR privilege level:

(undercloud) [stack@undercloud-0 ~]$ ipmitool -I lanplus -H 10.10.10.40 -U ipmiuser -P ipmipassword  power status
Set Session Privilege Level to ADMINISTRATOR failed: Unknown (0x81)
Error: Unable to establish IPMI v2 / RMCP+ session

Testing with USER privileged level works:

(undercloud) [stack@undercloud-0 ~]$ ipmitool -I lanplus -H 10.10.10.40 -U ipmiuser -P ipmipassword -L USER  power status
Chassis Power is on
