Bug 859520

+++ This bug was initially created as a clone of Bug #859512 +++

Description of problem:
:whoami operation not available for managed servers because the security context is not established by AS7. This operation is used by the plugin to detect the server state (need restart or reload).

The error is harmless but the plugin should attempt a different operation if this operation fails.


How reproducible:
Everytime for AS7 managed servers in a domain configuration.


Steps to Reproduce:
1. Start AS7 in domain mode.
2. Inventory a host controllers with managed servers active.
3. Execute an operation on one of the managed servers resources.

  
Actual results:
Operations succeeds but the the warning (shown below) is visible in the logs.


Expected results:
Operations succeeds, a warning is visible in the logs but plugin sends a second followup operation is sent to the AS7 server to check for the current status.


Additional info:
The operation to be executed in case :whoami fails is :read-resource. This operation is slower because the amount of data to be transferred from the server but it's safer since every single resource has it. This second operation is to be executed only if the first one fails.


Here is the full text of the error printed in the logs:
