About the Security Module
Users Page
The 
Users page gives you access to the platform’s user account library.
By default, the page opens when you click the 
Security module.
It gives you the list of the existing user accounts and enables you to edit and delete them and create new ones.
Your members are listed with little information like their username and job title. You can view information about a user account and the groups it belongs to by selecting it from the list. On the page that opens, you will only be able to change the member’s password.
|
User access rights are managed at the group level. Indeed, access to Saagie platforms, modules, and projects is not managed individually for each user account, but rather by the groups they belong to.
Groups Page
The 
Groups page gives you access to the platform’s group library.
The page gives you the list of the existing groups and enables you to edit and delete them and create new ones.
Groups enable you to manage the access rights. You assign roles to an entire group to allow members to perform some actions and not others. You can add as many members as you want and all members added to the group will have the same access rights.
Groups are listed with only their name. You can view and edit information about a group by selecting it from the list.
For more information on how to manage groups, see Managing Groups.
Saagie Default Groups

Lakehouse Catalog Access Page
The 
Lakehouse page gives you access to the Lakehouse catalog access library.
This page displays a list of existing Lakehouse catalog accesses and allows you to edit and delete them, as well as create new.
To be able to list the various information in a catalog and perform SQL queries on it, the user must have a minimum role assigned based on the action associated with the executed SQL query.
These catalog roles are, for each catalog and in descending order of privileges: an administrator role, a writer role, and a reader role.
This page allows you to easily create access to a catalog via its name, which will automatically create the three associated roles: admin, write and read.
Catalogs are listed only by name. You can view and edit the name of a catalog. You can also delete them.
For more information on how to manage Lakehouse Catalog Access, see Managing Lakehouse Catalog Access.
Lakehouse user roles are managed at the group level. This is because access to catalogs is not managed individually for each user account, but by the groups to which they belong.
