Raise session privilege level after the session established in revision 1.41 is not necessary for IPMI 2.0 session, but necessary in 1.5.
According to the IPMI 2.0 session establish flow, BMC creates the session with minimum privilege of requested maximum privilege level in RAKP 1, user maximum privilege and channel maximum privilege.
It means the privilege level is the maximum "allowed" level in the established session.
This command cannot be used to set a privilege level higher than the lowest of the privilege level of the user and the privilege limit of the channel.
Ticket moved from /p/ipmitool/patches/38/
Although the patch itself is not acceptable, this should be looked into and probably accepted.
This will have to wait. Patch seems to be out-of-date and code has moved on a bit.
