Using Authorize Project plugin I have setting we have "Project Default build Authorization" set to "Run as User who Triggered Build".
Then I have project roles letting particular users to run specific jobs. To allow said people to also build on the nodes I assign to them Slave role (see assign_roles.png). That Slave role is allowed to build on ".*" nodes (see manage_roles.png). But still when project is triggered from such a user, in the queue a message can be seen:
> 'myusername' lacks permission to run on 'my-node-name-1'
My workaround is to allow global Agent/Build permission to everybody but this is not ideal.
