A technique is provided for session aggregation in a distributed architecture having a server connected to blades. A master session is generated for collaboration by user clients, and the master session corresponds to one or more terminal sessions on the distributed architecture of the server connected to the blades. The one or more terminal sessions on the distributed architecture are aggregated in the master session. A determination is made that the user clients agree for one user client of the user clients to be authorized as a current command line user name, in response to requests that are sent to the user clients. The one user client is granted authorization to the current command line user name in the master session based on an agreement by the user clients.
