Create a new user in GUI

[jchmielewska]

We need a possibility to add a new user in GUI for Open Call participants. We want them to have access to our cluster but they need the separate user in GUI.

We've got a feedback from the use case partners that they will need that feature too. If they could login as the specific user and only view their applications.
