Operating System Users

Ondemand API, Library server

A workload is run using an OS account. This is automatically created in Linux, but must be configured in Windows, see the sections On Demand API and Library Server for details

In the case of these workloads, Altair SLC Hub will run the workload using the operating system user appropriate to the user that started the workload, that is, it will impersonate the end user.

Each user account in Altair SLC Hub has two properties, one that defines the operating system user to use when running workloads on Windows and one that defines the operating system to use when running workloads on Linux. For Hub user accounts that are synchronized from LDAP, these fields will be populated from the appropriate fields in the LDAP entry. For locally created Hub users, these fields can be set manually.

For LDAP users this means that each device in the system must be able to access these user accounts. This usually means the server is joined to a domain (although in Linux, you can setup SSSD without technically joining the domain).

In Linux, you may also configure the hub to use PAM, to ensure the OS creates users directories and audits sessions on workers. For more information see PAM.
