User management
Multifaceted user profiles
• Typically, a user (Admin) who will have no restrictions within the GridVis® is defined
• The Administrator can for example administer users and add or delete devices/topologies etc.
• Permits the specific assignment and deletion of each user's rights
• Defined access authorisations can be assigned through the rights
• Likewise, users are created and they are assigned rights or assigned to groups with this function
• The user administration can be agreed and set as an active function within a project
• Only one user administration can be defined for each project
• All users, passwords, roles and rights are held in one database (user directory).
• Multiple projects can be protected from one single user directory
• The individual rights of users are compiled in predefined roles (groups of entitlements)
• Roles (groups of rights) are cumulative, i.e. the rights of users from various roles are added together
• If a project is protected via the user administration, it is necessary to log in to gain access to the project
• Use of user administration within GridVis® is available in all editions (from GridVis® 4.0) except for the basic edition
