Normal user who has been assigned with the role** serveradmin** could access different components and perform activities like managing databases, changing different settings of the Server, etc.in the Virtual DataPort server.
Further, there are other predefined roles available for different tools like Data Catalog,Diagnostic and Monitoring etc. Based on the operation to be performed you could assign the required roles to the user. For more information about the roles, you can take a look at the[ “Default Roles”](https://community.denodo.com/docs/html/browse/8.0/en/vdp/administration/databases_users_and_access_rights_in_virtual_dataport/user_and_access_right_in_virtual_dataport/user_and_access_right_in_virtual_dataport#default-roles)section under Virtual DataPort Administration Guide.
Hope this helps!
