LogScale's role-based access control (RBAC) model enables authorization of users based on roles with different sets of permissions. We distinguish between authentication, which establishes the identity of the user, and authorization, which decides what are the actions an authenticated user may perform.
Access Control Concepts
The model is centered around these concepts:
Users
In LogScale, a user is allowed to do specific actions if one or more needed permissions are assigned them. Permissions can be assigned either directly to the user or via a Group of which they are a member.
Groups
Groups contain Users, which provide access for a single user. Groups collect multiple users together into manageable collections with specific permissions provided by Roles.
Roles
Roles define the permissions given to a user or a group of users across a range of access rights.
Groups are assigned roles in the context of a repository, giving all members of the group the permissions contained in the role. A user action on a repository is allowed, or authorized, if the user is a member of a group that has a role containing the needed permission.
At repository level, roles can be assigned to a user directly, without needing a group.
At repository level, Roles can also be assigned to a user directly, without needing a Group.

Figure 236. Authorization Concepts
If a user is member of more than one Group that has been assigned a role in a specific repository, the user has the combined permissions from the roles involved. So in the above diagram, Tom is both a member of Support UK and Devs DK which makes him an Admin and a Searcher in the Web Log repository.
Root access is a per-user property and independent of Roles and Groups. See Managing Root Access.
In LogScale, users are allowed to do specific actions if one or more
needed permissions are assigned to them. Permissions can be assigned
either directly to the user or via a group of which they are a member.
Permissions are always assigned in sets called
Roles
.
If you're the one setting up LogScale — either because you've created a new organization on Cloud-hosted LogScale and you're the owner, or you're a root user of an on-premise installation — you will by default have the permissions required to assign roles to users.
