POSTing to /api/12/job/[ID]/executions and using the optional parameter "asUser" used to work fine in Rundeck 2.6.1.
After upgrading to Rundeck 2.6.7, "asUser" parameter is ignored. The job is executed successfully but the user is not the one specified by "asUser".
The API user has "runAs" permission set.
confirmed, this is a regression
fix #1893 runAs should correctly set the user for execution
