I believe I was the person who originally reported this issue on IRC.

Daniel helped me debug as much as we could, it definitely appears to revolve around Roles being set for a user.

This is actually a huge blocker for our usage of foreman, where we want to give developers access to a subset of our machines. We want to give them total control of the hardware, including the ability to set 'ipmi_boot?ipmi_device=pxe' the host.

Ironically, the user who has Roles set for it, can easily 'reboot' the box so the BMC portion of the roles works for that, just not for setting the 'ipmi_boot' device.

Please let me know if I can provide any more information for this bug, as its easily reproducible in our environment.

Same issue with Foreman 1.9.0

This is a blocking problem for our shop as well - same use case as Kevin Mullin. We are using Foreman v1.10.

I've submitted a fix via https://github.com/theforeman/foreman/pull/3926 - I believe it's only the ipmi_boot action that suffers from this problem. The power_hosts permission works fine when applied to users in my environment. Let me know if that's not your case (and which version of Foreman you use)
