Administrators assign roles to users based on assignments and responsibilities. Set these roles in the application or map them from your identity provider if you have SSO integration enabled. If you start with a completely new Domino installation, the first user to log in is assigned the SysAdmin and Practitioner roles.
The available roles are:
SysAdmin - Administers instance with full administrative access.
ProjectManager - Manages organizations and project tags.
SupportStaff - Manages compute-related functionality.
System Librarian - Manages system artifacts.
